It was posted here, but it was a basketball doc, not about football players, and how fast the rehab should be was not discussed.
The Rams seem to have rushed two players back last year recovering from ACL tears. In the presser Fisher seemed to acknowledge that they would take their time with Gurley, and be conservative. What that likely means is that Gurley will start the season on IR with the ability to return - their one slot for that. He'll have to wait I think 6 weeks into the season then to start practicing at least which means that at the very least he will miss half the season. He might be worth it, but that means that 1/8 of his first contract will already have been used - plus figure he won't be a starter initially for at least a few weeks. So most of his rookie year is shot.
He may ultimately be worth it - before the injury he was a special talent - but that's a lot to give up, for a player at a position where the Rams have good non-elite depth while having holes elsewhere.
So yes, I'm concerned. I like Snisher, but at times they do like to act like they're smarter than everybody else in the room, so to speak, and gamble on raw players or health risks. Mitigating that with this pick is that it's a draft without a lot of exceptional prospects so they are giving up less opportunity cost than in most drafts, and that while it's a gamble that we won't be able to fully judge until 2016 (at least) IF it works out the Rams may have gotten the best player in the draft.
