I thought he was injured making a tackle. If so, leg stress had little to do with it. And I'm not sure I'd want Bailey injured either.
I'm not sure there is evidence that this is correct. At the very least, this post is making assumptions about the severity of the injuries that may not be accurate.
Harry was put on IR for roster management reasons, but if he was going to miss a couple of weeks anyway, it may not have been the worst idea. Wynn got put on after the team got the MRI results, so I'm guessing there was some ligament damage that was going to put him on the shelf for a few weeks anyway. Develin's injury does not sound like the type he would come back from. I'm guessing the same is true of Ghost's.
One thing about IR is that while a player on IR will miss 8 weeks, he can return to practice after 6. Players that are hurt enough to be listed as "DNP/out" on the injury report for 2 or more weeks typically have a couple of weeks where the are "limited/doubtful" or "limited/questionable" anyway.
