Absolutely; in fact most teams' draft boards should probably have many OTs ranked higher than their top-rated C/G, so if one of those Tackles remains available at 23 - Wirfs, Wills, Becton, Andrew Thomas, Austin Jackson, Joshua Jones - then common sense demands that the value lies there and who plays where on the Pats OL can be determined later...The highest-ranked C/Gs - Cushenberry, Ruiz, Hennessy, Biadasz - likely shouldn't be chosen until sometime during the (possibly mid/late) 2nd round...
Once we arrive at our 3rd-rounders, then the value difference between OTs & C/Gs is more evenly distributed...
