I gathered the info from different Twitter feeds:

Gill states the obvious:

Special teams is a disappointment.

Sims and Webb are the guys.

Gill talks about Defense:

Okay with the pass rush overall. (not sure about that one).

Gill talks offensive line:

Says pass blocking issues aren't solely on the o-line. I wander what he means there in the paper he stated this: “(On the punt) a guy who was supposed to block just didn’t block him,” Gill said. (As for the offensive line) we just got beat one-on-one. We had people there, and they missed their blocks. On defense it was the same thing, we just missed some tackles.”

Gill talks execution:

Team has to get play calls in fast enough. Some confusion with missed signals from sideline. Wants more cohesiveness out of play calling.
