Those juniors and seniors you mention also happen to be the best players that currently give Baber's and SU the best chance to win. Otherwise, if not, the underclassmen would be playing ahead of them, it's not just because they're upperclassmen. (See Coleman, Robinson, Black, etc. on D). Bottom line is you play the best guys that give you the best chance to win now...and many are Shafer's, especially at key positions; Dungey, Erv, Ish, Strickland, Franklin, Bennett, Samuels, etc.
That's great that the depth chart is filled with Baber's kids, hopefully that means good things for the future. However, if those kids were better than the aforementioned Shafer's, they'd be starting. That was the main point of my original post.
No doubt I think Baber's is a much better coach than Shafer and is getting the most out of his and Shafer's guys.
