Wildly inconsistent? His numbers over the past 4 seasons:
2004 368 carries, 1736 yards, 4.7 ypc, 16 TDs
2003 326 carries, 1435 yards, 4.4 ypc, 14 TDs
2002 295 carries, 1175 yards, 4.0 ypc, 16 TDs
2001 309 carries, 1318 yards, 4.3 ypc, 14 TDs
If that's wildly inconsistent I'd hate to see what consistent is. As far as Seattle making out like bandits in the deal, I fail to see how aquiring one of the best running backs in football is such a bad thing. Cedric Benson or whomever Seattle would end up drafting might end up being great, but Alexander already is. I'll take as close to a sure thing as you can get over the crap shoot of the draft any day.
I rather have a player who WANTS to be on my team.
