Well, the whole blow-up the roster or not is really just semantics. What does blowing up the roster constitute? Half the roster? Half the starters? More?
Like Half says you kinda have to look at it position by position and player by player. Which guys can you win with and which ones are weak links. You can't have a pro-bowler at every position, but you have to start by figuring out which guys are hurting you regularly.
Endaround kind of laid out the positives. I'll kind of summarize the positions.
-RB is OK but you could use a 3rd one at an injury prone position.
-QB is set for the moment, but you probably need to add one in the next couple of years.
-WR needs some help. You don't have much for slot guys right now. Cobb looks done. The rookies are OK and maybe one will be special, but I'd like to see them add a slot guy and maybe a stud outside guy.
-TE needs one more young guy.
-OL needs real help. Guys like Bell, Patrick and McCray are just OK as back-ups but should not be starters or the first guy off the bench. Even Taylor is a bit of a weak link, and Bulaga is OK when healthy, but I think he's about done, with his injury history. I think you need a minimum of 3-4 non-UDFA OL additions over the next 2 seasons.
-DL is just OK right now but you need at least a quality back-up or two. Another solid starter would be a plus.
_OLB needs a stud. CM3 is almost done and at best is a rotational guy now. Same with Fackrell. Sure he's put up some numbers, but does any DC really plan for how they will block him? He gets some sacks but does not apply consistent pressure so does not disrupt enough plays.
-ILB still needs a guy. Martinez is a winner. After that it's just guys. Burks was supposed to help, but he's not shown much.
-CB has a couple of guys. You might need one more quality guy.
-S really has nothing right now. Can Jones be a solid SS? Is Josh Jackson's future at FS? Brice seems like a decent back-up. You might need a starter . . . or two.
The way I figure it, you'll need about 7-8 top 2-3 round draft picks and another 8-10 later picks that work out at lower value/priority spots. Now, maybe you can fill some of those needs in FA, since you don't have many guys you really need to sign over the next couple of years to any real money besides Clark. No matter how you slice it, seems to me it's gonna take a couple of years until you can put together a roster strong enough to contend for a Super Bowl again.
