National Football Post's Wes Bunting has the Detroit Lions going the offensive lineman route in his latest 2011 NFL mock draft. Specifically, he has the Lions drafting Boston College offensive tackle Anthony Costonzo. Bunting's reasoning for this pick isn't that the Lions need to protect Matthew Stafford, but rather is based on the lack of cornerbacks worth the 13th selection being available.
13. Detroit Lions: Anthony Castonzo, OT, Boston College
The Lions would love to nab a corner here, but with questions concerning Brandon Harris' size and Jimmy Smith's character, getting a tough, athletic BC left tackle isn't a bad value at all.
If Castonzo were to be selected by the Lions, he would likely compete for playing time at right tackle during his rookie season. Interestingly enough, the competition would be with Gosder Cherilus, who is also a former Boston College Golden Eagle. While Cherilus improved quite a bit last season, recovering from knee surgery could potentially slow him down a bit this offseason and open the door for someone like Castonzo to make a competition out of the starting spot at right tackle.
