regular Joe's and their pre-injury form are nothing to brag about. It's a low bar Most of them couldn't do jack before the injury, so it's not a stretch to get them back to that level either. But even considering that, most regular Joe's are NOT without limitation even 9 months after injury.Ok, so this specific player will be about seven months removed from the date of his injury by the start of the regular season in September. By week 14 which is the latest a team could activate him to the 53 from pup list he'd be over 10 months removed from the injury and I'd assume at least 10 months removed from surgery.
I looked up recovery time from acl surgery, 2 to 6 months with it taking 9 months before you're at pre injury form. Now that's for a normal everyday joe or Jill not a NFL athlete. Even though he's 300 plus pounds I'd expect he should do better than the average regular guy but I'd also expect team drs to be cautious.
So realistically Simmons probably wouldn't even be on the 53 until somewhere close to week 14. What's he worth still #44 for me but I definitely would not take him before that
If he's as talented as everyone thinks, I'm ok at 44 too, but i'm not expecting a lot in year 1. Even if he is in great shape coming off of IR
