For the Vikings they picked:
Offensive lineman Kelechi Osemele
Osemele would be expensive -- the Ravens made him an "aggressive" offer, coach Jim Harbaugh said, and he could command about $8 million a year in free agency -- but he's one player on whom the Vikings might find a splurge to be worthwhile. Osemele is only 26, he has played both left guard and left tackle, and at 6-foot-5 and 335 pounds, he's a load for defensive linemen in the run game. If the Vikings had designs on parting with Matt Kalil, Osemele would make sense, and even if they didn't, he could be a force at guard. -- Ben Goessling
I love signing him and then follow it up with another pair of lineman in the draft. (one on day 1-2 and another on day 3.)
