I don't neccessarily agree with your philosophy on how to judge a draft. But, Smithiak has been pretty successful using your measurement. It's also worth noting what the Texans have done on the final day of drafting. It seems those picks are more value than you think (at least to the Texans)
Acquired with 4th-7th rounds
2006: OD, D.Anderson, KWalter
2007: Studdard, ZDiles
2008: D.Barber, C.Myers
2009: Quin, McCain, J.Casey
now, I don't think all of that list is "A" talent. But, getting guys like OD, Quin, and ZDiles late in the draft are good reasons not to be so eager to trade those picks in order to move up into the 2nd and 3rd rounds.
2007 was a horrible draft. No I dont like Okoye starting. In fact banking on Okoye ever becoming a playmaker is misguided. IMHO
The only starting caliber guy that was drafted is Diles and he was picked in the 7th rd. That tells me how bad the 07 draft really was.
2008 Brown is the only guy drafted that is starter level quality. That includes Myers and Barber. IMHO
2009 Cushing covers up a rather ordinary draft. Quin was a steal. The last 3 drafts have only netted 1 starter level guy. That's why Smithiak are 7-9,9-7.
This year I believe Smithiak drafted 2 starters Jackson and Tate. All of the other guys hopefully can help the ST's. That's why I would've traded the rest of the draft to trade back into the 2nd rd and make sure I got 3 day one starters out of ths draft.
