I tend to err on the side of loyalty. A part of me felt like Taysom needed/deserved his chance to prove himself, possible to make it in the NFL. Once it became clear that even at his best he probably doesn't make it in the NFL, my position softened. But, for no good football-reason, I felt like he needed a very, very long leash.
I think we see Tanner take snaps for several series in the near future.
