Either there is a huge talent drop off, or the guys behind them aren't getting developed the way they need to. Neither scenario is good.
We see a similar situation at QB, with KB's unwillingness to put Rygol in. Even when McCloud is performing abysmally, he refuses to put him in, or he does it so late that it's irrelevant.
Maybe it's just growing pains, but I can't help but feel it's a trend. Pretty concerning that he feels the backups at these positions are apparently so bad, that he has to modify the scheme away from what has been working, only for it to not work anyways, AND then the backups don't get work in the scheme that has shown success.
