It is known that the Buckeyes need a few more OL in this class to bolster their depth. Urban has stated on numerous occasions that the OL depth is not where it needs to be. It is not uncommon @ this stage of the recruiting process every year for the staff to put a few "feeler" offers out there, to determine interest level, as a back up plan, just in case they don't get OL #1, #2, and #3 on their board.
Just like the QB situation, they don't want to be left out in the cold when it comes signing day without a QB in this class so you need to have a plan B and plan C in place just in case. Culver is a plan B or C right now. and nothing wrong with that. We have had plan B guys work out well and become very successful @ OSU in the past.
