I too am disappointed about Sloter but there is a longer range possibility here... 
1. Chad Kelly. How does IR work? Will he get the reps, reps with the practice squad Sloter would have received or split? Also the last thing this team it seems would need is another QB battle discussion and confusion. He did this with Tebow, he got rid of him to focus and cut the what if's and the chatter. The structure is now set. He does understand locker room dynamics.
2. TJ Ward, he's been injured they have younger players they feel are ready, again no if's in the locker room. Structure is set. Focus can now be on preparing and playing.
Thoughts?
