Reasons DD is not a solid #1 RB:
1. DD is injury prone.
2. DD has 4 100 rushing games every year. I realize his YPG is high, but we need a RUNNING back. We need someone who can get more 100 yard games and help control the clock. Portis had 9 100 yard games this year which is the reason Washington is in the playoffs (and he can pass block - but he sucks for fantasy because he doesn't score)
3. DD is injury prone.
4. We need a RB that can pass block, which DD can't. If he could block better, Carr would have had a lot more time to throw to WRs instead of dumping off to DD. Side effect: As our OL improves, we should throw more to WRs and less to RBs, which means DD value will decrease
5. DD is injury prone.
6. DD does not break long runs. Even when DD gets a big hole, he gets caught. We need a RB that is threat to take it to the house if he breaks through the line. DD had 2 games this year where he had 44 yard runs, and didn't score (note that both of these games were against Tenn who was terrible this year). His next longest run was 29 yards, and didn't score (against Balt). After that his longest rushing gains per game were: 19, 18, 15, 13, 12, 11, 7, and 6 (nad his previous years are similar). His longest pass catches were 30 and 33 yards. He just isn't fast.
7. DD is injury prone.
8. DD does not score rushing TDs. He had 2 rushing tds all year. Arguably this is an anomaly for this year, or it could be a trend.
9. Did I mention DD is injury prone?
Untrue Bush comparisons:
(I think everyone admits he is fast(4.28 40), can catch and has awesome juke moves - I taped his games against UT and UCLA and watched some of his runs in slow motion, the only thing I could say is WOW) (before watching those games I was in the "trade the pick" category, as I have been since year one)
1. He can't pass block: The dude is a great blocker - as other posters have attested to.
2. He is too small and weak to go inside: He benches over 400 pounds, is 6 foot and 220 pounds. According to CBS: Alexander is 5'11 and 220; LJ is 6'1 and 230; LT is 5'10 and 220; Tiki is 5'10 and 200; EJames is 6' and 215. So, it's not his size or strength that is the problem (Carroll played to the strength of each of his stud RBs - Bush's speed and White's size - but that doesn't mean Bush can't get his inside - watch the UCLA game film for proof). Also, like most RBs, he will add about 20 pounds of bulk over the next two years.
3. He is too . . . . err... that's about it.
DD's limitations aside, I have no problem keeping DD, as a complement to Bush. If we can't get anything for him, keep him (and trade Morency for a 4th or keep him too). It would be nice to have depth and strength at a position (especially RB due to the higher injury % for RBs).
One last note: RBs that are pass catchers (Tiki/LT/DD) will always rank high in fantasy, but that doesn't make them the best in real life. I remember the king of YPG - MFaulk in his prime. DD is no Faulk (and neither is Tiki or LT). Bush might not be, but then again he might be. I would just be happy if he is the next Terrell Davis (especially with Kubiak here). I drafted him #1 a couple of times.
