When he was a starting LT (albeit as a rookie), Coleman was solid (0 sacks, 1 QB pressure across his starts, but overall 64 PFF -- 51/89 Ts --

I hope Coleman has improved (and I've always liked him as a player) because if we're trotting him out at LT, his pass blocking is going to need to improve a lot since his rookie season. Not saying it won't or can't, but if it hasn't, I wonder whether they're considering moving him to RT and sliding Conley over to the left (as word is that he's really taken a step forward this year, under Tunsil's wing). I know that's not a simple fix, but it is still a month away from week 1.
