It's too small a sample size to say they have had a lack of success with First Rounders.
-Thomas is a future Hall of Famer.
-Okung is one of the best LTs in the league when he is healthy.
-Irvin hasn't proven his worth, yet, but he did have nine sacks and 19 QB hits as a rookie, and he did start 14 games at SLB last season. With two years left on his rookie contract, his status is still TBD.
-Carpenter has been a bust, at least in part due to knee injuries. But he did start 26 games. That's worth something, right?
90% of teams would take these results with four draft picks because being a First Rounder is no guarantee of success. Every year, about half of all First Rounders fail to meet or exceed expectations. They knocked one pick out of the park, nailed a second, and the last two picks at least became starters, albeit disappointing starters.
I hope they take the player available who is most likely to succeed in their system.
