I could get on board with a scenario like that too. I'm holding out hope that Barkley wows everyone on his pro day though. If he or Geno is available, I'd take it. Then again a nice defensive guy and QB in the second could work. I'm no expert but I do like BPA when it's a position of need. On the surface LT is not a position of need but Glenn was considered the best guard coming out of college with most people(Bill's excluded) not thinking of him as a tackle.
To sum things up, there is more than one way to skin a cat.
