Bieber is kind of cooked.
There was some hope that he could return to form, but that ship is sailing.
It’s important to remember that his TJS masked a decline that was already happening before the injury. Now it’s been almost 2.5 years since the surgery and he still hasn’t gotten back to where he was. At this point, it’s getting pretty hard to see that happening.
Look at it this way: he took the $16M player option last year, and since then he’s had an even worse season with even more injury and reliability concerns piled on. He’s another year removed from TJS and still hasn’t gotten back to form. Even his projections are pretty mid at this point and we couldn't even trade him for a sack of marbles at the deadline.
If you sign him, can you even reasonably expect him to get through spring training healthy, take the ball every fifth day, and give you 150+ innings? Hell no. And if you’re paying a starter $22M, you should at least have some confidence that he can do that.
