I'm on the trade down for picks band wagon.
So, in regards to the debate over Bush, I've got 2 words for you.
Barry Sanders!!!
In my opinion, Sanders is one of the best, most electrifying, RB's in the history of the game. But, even he couldn't carry the Lions to the Super Bowl. He played for 10 years from 1989-1998 & yet, the Lions finished above .500 in only 6 of those years. They made the playoffs in only 5 of those years & had a playoff record of just 1-5. Even in Barry's best year, when he ran for 2,053 yards, the team went 9-7 & lost in the first round of the playoffs.

1989 (7-9) .438 3rd NFC Central (1,470 yards)
1990 (6-10) .375 3rd NFC Central (1,304 yards)
1991 (12-4) .750 1st NFC Central (1,548 yards)
1992 (5-11) .313 5th NFC Central (1,352 yards)
1993 (10-6) .625 1st NFC Central (1,115 yards in 11 games)
1994 (9-7) .563 3rd NFC Central (1,883 yards)
1995 (10-6) .625 2nd NFC Central (1,500 yards)
1996 (5-11) .313 5th NFC Central (1,553 yards)
1997 (9-7) .563 3rd NFC Central (2,053 yards) (only 5 RB's in the history of the game have rushed for more than 2,000 yards in a season)
1998 (5-11) .313 4th NFC Central (1,491 yards)
Imagine what he could've done behind the line that Emmitt ran behind. I'm sorry for the draft Bush fans, but there's no way that one player can carry a team in the NFL. Unless, of course, his name is Earl Campbell.

We've got to rebuild the OL & this is a great year for doing it.
