If Bedard is the best writer we've got, than we're in trouble...
First make up your mind Bedard, we're a 3/4 or a 4/3, if we're a 4/3 like you've suggested than Wilfork isn't a nose tackle, he is just a defensive tackle. If Deaderick is a nose tackle (he's not close to a nose), Love is a starter and DT is only the 5th "need" than you don't know what you're talking about and haven't been watching the past 5 years of Patriot football.
Let's just admit that this team won't win a ring being an "offense first" team, Parcell's was correct when he told BB to get back to his defensive roots. If we really want to improve this defense, switch this depth chart back to a 3/4 and use the 2/4/5 in nickel situations only... which makes DT priority 1-A along with SS and getting a corner.
Kafka won't be on this team when the season starts.
Flex tightend isn't a position, you have tightends and fullbacks in our system, call the fullback an H-back if you like, but at the end of the day they are fullbacks. Our best fullback after Hernandez is Huey, he should be a priority signing IMO, he was crucial in our improved run game this year and can be had at a very reasonable price. If we have Huey than we don't need Aaron to play FB, decreasing his chances of being hurt. Hernandez plays all three positions well and is in a class by himself.
If X receiver is the guy who plays out on an island by himself than that has to be priority #1, Lloyd if he is kept can be moved inside to play the Z, but if we really believe receiver is priority #1 (which I don't necessarily agree with) than go big (talent) or go home.
IMO Lloyd with another year in our system will be much more comfortable and improved. We could come back with the same exact set of receivers that we had this year and would be fine, we'd still be the #1 offense in the league, would that win us a ring at the expense of defense, I'd say no.
Defense still wins championships. It's an offense first regualr season and an old school defensive grind in the playoffs. Get beef, get a DT in the draft or free agency and load up at SS and CB. Everything else is an after thought.
