Hate to be negative, but shoulders never heal fully after a surgery. They patch your shoulder up so it doesn't affect your daily life, but throwing day in and day out through a full season isn't gonna happen. Range of motion shortens and chance of re-injury is significant.
If this were Rookie of the Year, I'd say we sign Nichols and snap the tendons of the rest of our rostered QB's, but sadly, this injury is like me messing around with fireworks and messing up my best typing finger, my job is gonna suffer. ( I got pretty liberal with the analogy, but hey, internet stuff is fun)
