Glad you came up with those stats Prophet. I think we'd be better off spending the big $ on FA OLinemen and drafting them after the first round. Unless there is an LOT on the board that just appears too good to pass up, I'd stay away from OL early in rd. one.
Now, we could always trade down in the first round if we really want one, but still, a rookie OLinman from the first rd. is going to be expensive, and it's going to take time for them to develop. That means we'd be paying a ton of $ for a guy who's going to take some time to contribute.
