1. Tom Brady will be back. Matt Cassel played well. Extremely well, however he was not able to fully utilize the deep threat to Randy Moss. Cassel is a great accurate, dink-and-dunk quarterback, similar to Brady when Tom was younger, however Tom can make the short throw AND the long throw. Cassel was great, but Brady is better.
2. Our Running Backs will be healthy. Okay, last year was crazy. Three out of our four running backs were injured, and all for significant periods of time! No way that happens again. Even if one, or two go down, we have a lot of depth there. Sammy Morris is a great runner for 4-5 yard carries, consistently, as he is fairly quick and packs a punch when he runs into a defender. He also is very good at hitting the holes. Lamont Jordan is a great guy for those tough, 2-3 yard situations, just because of his size and because he’s so hard to bring down. Laurence Maroney is good for 5 yards a carry, if he achieves his potential. He can run over defenders, juke them out, and has a powerful stiff arm move. If BB can utilize these three running backs so that Jordan gets 4 carries a game, Morris gets 10, and Maroney gets 10, meaning they split the load, then they will stay healthy and fresh. Plus, Kevin Faulk can always be thrown into the mix. If any of the backs get tired? No problem, there ar at least two more capable starters. And yes, I believe that Maroney will stay healthy this year, as will Morris, as both are learning to keep their bodies healthy, specifically Maroney, who is learning that it’s better to get tackled than to get injured.
3. Our cornerbacks are good. Ellis Hobbs is a solid corner, and can cover pretty much all the #2 wideouts in the league, and can occasionally shut down a #1 guy. He is a little bit slow on the deep ball, however with Brandon Meriweather’s ball hawking skills and recovery speed, that should be less of a problem. Also, Jonathan Wilhite showed promise at the end of last season. He was able to intercept the ball, and make some big defensive plays. He is a great option to cover the #3 receiver, and occasionally the #2 wideout. Now, not he showed his rapid improvement towards the end of last season, and if he continues to improve, he can become a very, very good corner in this league, because of his instinct. Lastly, Terrence Wheatley was getting better before he injured his wrist.  He is very similar to Wilhite, except that he is a little bit more of a speed corner as opposed to a wrap-up tackler. He is a good tackler, and if improves at the pace he was before he got injured (He shut down Reggie Wayne while playing the Colts before he went down), then he will be a great corner in this league, even a shut-down one. Just because he wasn’t a first rounder, doesn’t mean he can’t be good. Even Jonathan Wilhite. Remember, Asante Samuel was a 3rd rounder.
4. The safeties will be better. James Sanders is improving, and Brandon Meriweather led the team in picks (4) despite only starting 10 games. Sanders is a good, consistent tackler, and Meriweather is a great ball hawk, who is quick and has developed a real knack for the ball. He is working on his tackling, and once he becomes a better wrap-up tackler, his occasional big hit will be glorified. Also, Tank Williams, who was overlooked to to his pre-season injury, is a great safety. He also can play linebacker if need be, and he is a very, very consistent tackler, who posesses enough speed to flow with tight ends and most wide receivers.
5. The line is good. Both lines. The offensive line last year was great after getting used to Cassel’s style, and with Brady back, (or even with Cassel if Brady can’t go) then they will dominate, similar to the ’07-’08 season. Last year, we saw what the Pats defensive line could do with the three men healthy. Warren did go down towards the end of the year, however when they are healthy (which they were for 14 games last year, and will do the same next year) they are dominant. Richard Seymour. Need I say more? Quick, powerful, great at batting down passes and rushing the passer. Vince Wilfork is just a mountain in the middle, and Ty Warren is an underrated run stuffer, who has the ability to get to the QB.
6. Ben Watson will be better. He will be used more offense, as he has become a better blocking tight end, and his route running has improved. He is a great run after the catch tight end, and like Antonio Gates, is very athletic and very fast.
7. Our linebackers will be better. Jerod Mayo will improve, Adalius Thomas won’t be injured, and Mike Vrabel will at least be consistent. Also, Pierre Woods will be a stronger back-up, and a more useful option after his experience last year. Also, Gary Guyton showed promise according to Bill Belichick before getting injured, so he will provide some depth. If Bruschi can come back after his injury, great, he is not great anymore, but he is good, and knows how to play. Also, the Pats will probably address their linebacker issues in the draft, even with Rosevelt Colvin and Junior Seau.
8. The defense will be deeper next year. Similar to last year, the Pats will probably go all out defense during the draft, to address depth issues at linebacker and safety, as well as grab a #3-#4 cornerback. The Pats will either go safety or linebacker in the first round, and whichever way they don’t go, they will probably choose in the second. I think they will choose a linebacker in the first round, especially after how well Jerod Mayo played last year. Then, in the 3rd, they’ll probably go for a corner, and in the 4th and 5th round they’ll look for secondary players in general. Because they have Tank Williams, who can play linebacker, they don’t need to draft 3-4 backers this year, rather only 2-3. That’s why I think they’ll draft a backer in the 6th round, and then leave the 7th round up to possibly a special teams guy who’s primary position is cornerback.

I think this is how the draft will shape up:

Round

1. Linebacker

2. Safety

3. Cornerback

4. Cornerback/Safety (somebody who has the versatility to play either)

5. Safety/Cornerback (same as above, however more of a safety)

6. Linebacker

7. Lineman/Small Linebacker

Overall, the Pats will just be better defensively, and will be able to utilize all of their weapons offensively. Even though the Pats lost Pioli and McDaniels, I believe that that the coaching of Bill O’Brien will be fine in replacing Josh, and Belichick has a very similar and uncanny knack for getting a steal pick, similar to Pioli.  Plus, I don’t expect the Pats to get hit with 20+ injuries again this season. And when healthy, this team has shown (2007-2008) that they really can’t be beat*. So, if the Pats made, and almost won the Super Bowl* with an extremely similar team, which has an improving defense, then shouldn’t they be able to do it again?

• *Note: The Giants won because of an attrocious offensive game, and the David Tyree catch 1) never happens again and 2)Richard Seymour and Ty Warren were being held on that play (look at the replay)
