Holy ****, read this whole thread. I just did a quick PubMed search and that syndrome is real and indeed seems to match with much of Fultz’s apparent problems.
One article says it can take 2 years to fully recover when managed conservatively. I don’t know if he’s been managing conservatively enough, or even using appropriate techniques (doubtful), but it would be incredibly Philly to trade him and watch him just come back to normal as he reaches the typical healing timeframe.
