I might be wrong, but I thought they divided the team up into groups for practices so that they ran different stations and GA types may handle majority of walk-ons, not impacting reps for anyone?
One case for numbers is to have the best quality scout team put together for practicing.
We’ve had times over the years where we can barely field a three deep at a few positions with injuries and whatnot. That moves some other guys up the ranks for depth, and you could run short on scout teamers pretty quick I’d imagine.
The changes with redshirting also would impact this dynamic I imagine.
If numbers are getting in the way, I’d agree to trim it down. But if properly managed, I like throwing as much as you can at the wall to see what sticks.
