I, for one, would love to see Tomlin continue his progression from the WR whisperer to the QB... uh... quiet talker. I thought he handled the Fields/Wilson situations about as well as possible. They both have serious holes in their games, but Tomlin still guided the team to another playoff berth with that two-headed monster, without letting the thing turn into a sideshow.
Even though people don't like Rodgers (I guess because he experiments with ayahuasca rather than vaccines) he is still head and shoulders above what Pittsburgh was running out there last year. And I think he would fit right in with Tomlin. The problem in NY is there was no leadership, so he took the reins. That won't be the problem in Pittsburgh.
