This analysis is wrong, because you're cherry-picking the top producing rookie RB. If you look at RBs who were chosen #1 or #2 overall (going, therefore, to bad teams like Reggie Bush is going to), you'll see:2005: Ronnie Brown (RB#18)Oh boy, ruffled up the LT clain again.
This is by no means as outlandish as the LT supporters would love to think though. RBs is one of if not the EASIEST of all positions to transition from college to NFL. Bush is going to be one of if not the highest ranked prospect ever at the position. Several other rookie RBs faired as well or close as the OP is debating Bush to:
year, player, RB rank
89, Sanders, 4 (15 games)
92, Watters, 8
93, Bettis, 2
94, Faulk, 4
95, Martin, 2
96, Abdul-Jabbar, 9
96, George, 8
97, Dillon, 8
98, Taylor, 4
99, Edge, 1
00, M.Anderson, 4 (14 games)
01, LT, 7
02, Portis, 4
1995: Ki-Jana Carter (RB#34)
1994: Marshall Faulk (RB#4)
1990: Blair Thomas (RB#39)
1986: Bo Jackson (RB#28)
You have to go all the way back to 1983, Eric Dickerson, to find a RB who was drafted in the top two picks, who finished as a top-3 RB in his rookie season.
If Reggie Bush falls in the first round to the fourth or fifth pick, he might have a shot, but there is zero chance he leads the league in fantasy scoring or comes close while playing for San Francisco or Houston.
