Kiper hands out his draft grades

Instant Impact from Cowboys Draft (2:14)

Todd McShay explains why Cowboys fans should be thrilled with their early draft picks (2:14)

ESPN's Mel Kiper Jr. has come out with his draft grades for each NFL team. He handed out two A's, to the Seahawks and the Ravens.

He gave the Cowboys a B-minus, praising the Dez Bryant and Sean Lee picks but showing concern about one remaining area of weakness:

But unless they do something in the interim, the Cowboys will head into camp with Doug Free as the best left tackle on the roster, and while the team likes Free's potential, Tony Romo's blindside protection is still a concern.

ESPN.com also has a new formula to evaluate and rank how each team did in the draft. It factors in team needs and veteran players acquired in trades for draft picks. The Seahawks are No. 1 in these rankings. The Cowboys were tied for No. 7, second best in the NFC East behind the Redskins (tied for fourth). The Eagles are ranked No. 14, and the Giants are all the way down at No. 30.
