I actually don't think it's an injury with Nichols, I think it's Harris and Dressler more than anything else. It's no secret that those two guys are tailor made for the offense that Lapolice likes to run, and they have put some hard hard miles on Harris' body this year. I suspect that he is hurting but soldiering through it because that's the kind of player he is, and with Dressler out that's one less crutch in the offense. Lapolice of course has never been good at adjusting and adapting so without those guys being at 100% the offense is faltering, especially when teams know that taking away Harris is priorities 1-6 in their defensive game plan.
