Hyperbole your thing this morning?
I didn't say there was a perfect system. Not sure what the "ideal" bell curve is. I'm just pretty sure rotating only 4 guys then having to hope that 2 other guys step in cold off the bench and perform when injuries happen isn't it. And you really do have to consider whether guys with talent and potential will stay around knowing you only play 3 or 4 WRs. UT can't be perpetually thin at WR. The loss of two guys this year probably cost the Vols a game.
I love Heupel and how he runs his O. But the Vols ran 3 legit options at RB with only one spot. Until forced by injury, they ran 4 guys for 3 spots at WR. That's a hole... a flaw at least in terms of developing and retaining depth.
Did you really just try to use UGA as an example of "unproven" guys stepping in? You might want to take another look at their roster. Bama too for that matter. They play A LOT of WRs. They aren't all stars. But they're all getting time and feel for the game.
