Tom Pelissero has an interesting column up on the actual impact high draft picks can have on the teams who select them:
The NFL is designed to promote competitive parity, from the salary cap to revenue sharing to a draft order inverted by record and strength of schedule.
However, it remains a league of haves and have-nots in many ways. Look no further than the inability of roughly half the league to capitalize on the sorts of opportunities the Minnesota Vikings have with the No. 3 overall pick in this year’s NFL Draft.
Since the NFL playoffs expanded in 1990, 17 teams have made multiple top-three draft picks, accounting for 56 of those 66 picks (84.8%) overall. Only three of those teams — St. Louis, Indianapolis and Washington — have won a championship.
The other 15 teams have combined for 32 Super Bowl appearances, including 19 of 22 titles (86.4%).
In other words, no amount of talent can fix a bad team if the team is bad for organizational reasons. Management/leadership matter more than raw talent, at least in NFL terms.
