Draft: Need vs. Best Player

[warriorzpath]

One reason I ask this is what happened in last year's draft. It appeared that after the draft, there was a lot of criticism for Houston by picking based on need instead of best available player (Mario Williams instead of Reggie Bush) - enough to pressure (self-imposed ?) Casserly to quit soon after.

Basically, if you were given this scenario again, would you pick Williams or Bush ? And it's okay to cheat and use last year's performance of both the team (Texans/Saints) and players (Williams/Bush) to decide.
