He cannot function when he isn't totally healthy.
When fully healthy, he's elite. But he regresses to a bottom 10... maybe bottom 5 starter if he is dealing with anything that restricts his mobility, and in a 17 game season, keeping him untouched is essentially impossible.
Overall, they've been better than I thought they'd be. The surge in early autumn gave me some hope, but it all died after Kyler got hobbled in Seattle.
I can give him an "attaboy" for playing banged up, but if he is terrified of taking a hit then he shouldn't be out there, he shouldn't be in the sport.
