Who are you and what have you done with Bob?
Ok, I was expecting at least 700 words. I like what SF has done so far. I don't know if they are the most improved but they certainly have the most room for improvement.
i was inhabited by a concise, terse presence... its gone... i went out for a little exorcise
...MIN, DAL & KC are clear examples of teams that helped themselves both through free agency & the draft.
SF is good example of team that should improve through other factors... internal improvement (julian peterson, ahmad plummer & mike rumph missed large parts of last season) & coaching/system change.
i don't know if their turnaround will be as dramatic as above three (i think jamie winborn could be a key piece to the puzzle if he can stay healthy... 30-40% chance of that... also tony parrish is talented & could be poor man's ed reed for ex-ravens DC nolan), but they could potentially be in the top half... maybe top 10 in another season, contingent on drafts & more FA acqs (they were until recently notorious cheapskates, but the owner wife read riot act to skinflint husband & made him break the piggybank). the problem is their offense will almost certainly the worst of any of the teams i cited above & will below. that could put tremendous field position pressure on the defense early & often. they could get worn out in-game & over grind of season if a lot of three & outs leads to them being on field disproportionate amount of snaps.
i almost mentioned CAR. peppers is a monster who is mutating into an alternate football life form in front of our eyes. last year was the year the light went on... he should redefine the position like deacon jones & reggie white did in their generation. jenkins is a pivotal player because he helps peppers & rucker (bounceback year?) get more pressure on QB by collapsing pocket... & by implication this helps everybody in secondary, morgan could lead the league in tackles if he ever plays close to a full slate of games (he was pacing to shatter his former record before missing about third of season... AGAIN), witherspoon quietly put up takeo spikes-like numbers, they added ken lucas & with chris gamble could be one of the best CB duos in NFL after BAL & MIN... & SS/OLB/rover thomas davis is a BEAST... by himself he will be an impact player, as will my co-favorite for defensive ROY... former georgia teammate odell thurman for CIN.
they could be greatly improved (about #26 against run last season) with another GA teammate, david pollack & the potential improvement of massive talent madieu williams.
though not on the same scale, if bob sanders can stay healthy & marlin jackson is as good as advertised, the colts will have a better overall defense in run support as well as coverage.
i think the rams could be better if jimmy kennedy builds on end of last season, little & hargove approach 20 sacks between them, claiborne/tino/coakley mesh at LB, travis fisher stays healthy & comprises underrated duo with jerametrius butler & somebody clicks at SS with archuleta... i hope atogwe.
CHI will be better... o-gun, uhrlacher, mike brown & peanut tillman missed a lot of time... STL led NFL with 46 takeaways lovie smith's last season as DC with rams in '03...
i think NO could be improved but know i am contrarian... grant, smith & howard have to be best DE threesome in NFL, courtney watson could be a good one at MLB or WLB (i like the latter to get fincher on field), the team didn't give up less than 20 first 12 games or more than 18 in last four... that coincided with stronger CB play from in-season FA mike mckenzie & the anonymous fakhir brown... dwight smith was an underrated but potentially high impact FA acq, rookie safety josh bullocks has looked good in coverage & will be useful in nickle & dime packages.
ATL was already good (led nfl in sacks)... coleman hopefully won't flip his car in-season, 2nd rounder babineaux led big 10 in sacks & was among national leaders in TFL... i think he will be one of best DTs from class along with patterson... ed hartwell & d-mo are upgrades at two of three LB positions, hall could be elite cover CB... they need bryan scott to get through his shoulder rehab by the start of the season.
