Whenever you can get a potential pro-bowl caliber talent, that plays in a position of longevity (such as offensive line or defensive line), I say go for it. Is that person Iaputi? Heck if I know, but if Bill thinks he is, then I support that decision. Essentially, that is where the value is at! There is less value in drafting a kid like Best out of Cal and getting a year or two out of him before he limps his way out of the league.
I'm used to the days when BB would address the offensive line late in the draft and via free agency than use a first round pick. Him taking Mankins, blew my mind and I wrote of the picking of Matt Light because it was a second round pick and he was a solid talent at that time.
Overall, I'm not used to Bill's draft strategy. Trading up for Chad Jackson seemed silly and was a failure. The Pat never really drafted LBs under Bill either (unless you want to count Ted Johnson), but then they draft Mayo (albeit after trading down).
