At the risk of sounding ridiculous...
Is there too much depth in the offensive skill positions? I mean, being able to absorb the inevitable injuries with quality depth who are basically as good as your starters is great, of course. But until that happens are you hurting the rhythm, explosiveness, and continuity of the offense by not being able to focus snaps and touches with your "top" few guys?
To illustrate, I have Meyers with 100% of offensive snaps yesterday, and Humphrey beating out Bourne. At TE, Smith saw more snaps than Henry, and Stevenson more than Harris at RB. If I had suggested those two weeks ago, all but maybe the last one would have been met with much head scratching and hand-wringing, no?
Or maybe the idea is that the chemistry will develop at different rates, but by the end of the year you've developed a deep well of connections that everyone trusts and feels good about.
I do know that having so many weapons doesn't help that much if the QB locks in on a couple of them. Hopefully the OL can make Mac feel comfortable so he can get back to scanning the field and just going to the open man again.
