The 9ers have been awful to watch. Here's their "weapons":

The idea was for them to be a ground and pound kind of team.
I think JG alone can't turn that team around, and of course one down side for the 9ers is that he just used up their 2018 2nd rounder so they don't have as much draft capital.
We have a bye week to figure out the whole backup thing. Hoyer was going to be part of the trade but the 9ers released him instead due to issues with potential compensation picks. I guess since Hoyer is now a free agent, if we (or anyone else) signs him the the 9ers are entitled to compensation. So, we'll figure it out.
