I believe one of the coaches shocked me and said Gary could also be used as ILB, but I feel like that was just talk, otherwise why didn't you do it at all, all season with a huge need at ILB. Actions speaking louder than words for me there.
But Gary is very straight lined player, struggles to turn, that'd kill him in man coverage, and might in getting to and filling the hole... so I think he's a horrible fit at ILB.
I much much rather put Z., P. and G. all on the field at once... via putting Z. or G. at DT next to Clark like they did with Z. this season... or P. at ILB, as he'd be the best in coverage.
Of course, I think it's simply Gary wasn't ready, as Fackrell kept getting the call over Gary.
