re: Can we expect a drop off in RB talent coming out of Louisiana

I can see what you're getting at. Although, I don't think this will take effect until years down the road. No doubt the game is changing to a less RB-friendly game, so the need for other positions is greater; also, the career of a RB is much shorter than most positions, so I feel that you will start seeing more and more kids being pushed toward playing other positions.
