Frankly, I don't think they have had a good set of 3 WRs since Delhomme's first year... and in fact they didn't even have 2 good WRs in the other 4 seasons. And the top TE in the first 4 of those seasons was Kris Mangum, when Delhomme was healthy... so no real help there.
Now... we can obviously differ on how good Hackett is, but IMO Hackett at #2 and Muhammad, even at age 35, paired with Smith, gives Delhomme the best set of WRs he has ever had. And King is an upgrade over Mangum, too.
I agree Williams is unproven, but I think he has shown good potential. As long as he is serviceable, the offense should be much better; and the improved passing offense should help him. If Delhomme comes back healthy, I think there is some fantasy value in this offense.
WR : I'm not so sure if Hackett can be penciled in as a legit #2 WR or how much of an upgrade over Carter/Colbert last season. If he's such an upgrade over Drew Carter... why did Drew Carter get roughly the same FA $? TE's : Changing from bad to bad isn't progress. Just ask KC fans that swore they had upgraded their OL in '07 because they weren't starting the same group that started in '06.
QB : Jake should be back but he's 33 and so far his career looks like a bell curve that peaked in '05.
RB : Worse than last season even to those that weren't a fan of Foster.
Good signing by CAR but I'm not sure how much of an upgrade they've made on offense. From a fantasy perspective I'm not even sure if Hackett produces as much for CAR that Carter does for OAK this season.
reportedly CAR assured hackett he would start opposite smith (which isn't earth shattering, i'm sure many would have expected him to start), & that probably factored into his decision... though not sure who would have started in front of him in TB opposite galloway, & randle-el in WAS probably better fit as slot WR, he may have been favorite to play WR2 there, too...hackett was hindered by a high ankle sprain most of the season... hurt it game one, played three exceptional games, than reinjured it & didn't do much thereafter... so he is a question mark in terms of durability... but he has flashed some serious talent in limited action... in three healthy games, he had something like 20+ receptions & a TD in each game... carter had many more games played, but i think had as many as 5 receptions once all season (he was no doubt hurt by delhomme's absence)... he is faster than hackett (& has elite speed), but in comparing them, carter doesn't look like he has as natural hands, is as comfortable inside, or as versatile a route runner & weapon...
as for delhomme, 33 isn't ancient for a QB...
deangelo may not have proven he can carry the load (as a pro), but i don't think there is much cause to assume he will be a downgrade over foster (maybe you meant they have less depth at position now with foster's departure?)... he has had a higher YPC average in limited action, & by the eyeball test, appeared far more explosive & dangerous in the open field...
deangelo is dissed by some for being a tiny scat back, & not feature RB material (actually a lot of RBs aren't feature RBs in a conventional sense anymore, with many in a RBBC)... i think he is roughly the same size as emmitt smith was when he came out of college, with similar stocky, compact, powerful lower body with mammoth, tree trunk legs... he also has the speed to take it the distance... he probably isn't as fast now, but i think he was fastest arkansas prep in his class (about a 10.7 or 10.8 100 m)... some RB attributes i like even more, at his best he flashes very desireable RB traits such as vision, cutback ability & natural running instincts...
for those in thread who haven't seen him in a while & forgot or never saw them, here is youtube highlights... my favorite run was about 1:30 mark, replayed a few times... in last version, he makes four cuts from left side to pop free down the right sideline for a long TD run... at the 2:54 mark, look at how quickly he scoots into the second level, gets on top of the safeties & splits them, than explodes past them in the open field...
memphis may not have faced the most challenging competition, but at his senior bowl & combine deangelo showed he was a man among boys and dominated the RB class*...

CAR has had a marginal run game since the wheels came off stephen davis, partly imo due to detriorating OL play, but also fox's stubborn insistence on featuring the less explosive foster (in fairness, deangelo may have need some work in pass protection, as do many young RBs)... IF deangelo makes good on his opportunity & shines like he did as a highly graded collegiate, this could help the passing game a lot more than some here may be accounting for...
& of course that works both ways... if hackett can stay healthy & proves the best complemement to smith since a younger mushin muhammad, this could do wonders for the running game, & help spread the field more... deangelo is at his most dangerous in space, on plays like screens & draws... on some of the plays in the highlight package he is reminiscent in physical stature & movement skills of brian westbrook... they are both bigger than you think (so to speak), deceptively strong & won't be arm tackled... it usually takes a solid shot to bring them down (which is not always easy to get by a DB in the open field, due to their outstanding vision, instincts, cutback ability & elusiveness)...
* edit/ADD - this part may seem overreaching... bush (& i think maroney) couldn't be at senior bowl, & bush went far higher... i'm sure some front offices valued bush more overall due to his faulk-like receiving skills... & bush also extremely dangerous in space with his open field running skills (but seemingly not as good getting through the OL & untracked)... however, i also think it likely that some front offices found williams to be better PURE runner... in college he was a standout in a class that has featured some pretty good young runners, including maroney & addai...
