My guess is that even though his ACL rehab went well, when he started to put a real game workload on that hamstring, it just wasn't ready. This is a brief explanation from one of the medical articles I read when using part of the Hamstring muscle to surgically repair the ACL.
To figure this out, researchers looked at 24 patients and took very detailed post-operative MRI images of the tendon and muscle and strength measurements. What they found wasn't great for patients who get their ACL's surgically reconstructed. The good news is that the tendon defect regenerated and filled in for 21 of the 24 patients. The bad news is that the hamstring muscle was 12% smaller and 25% shorter than the non-operated side. In two strength measurements, the hamstring were >30% weaker as well. Another study in 2012 showed similar, but even more substantial issues. In a much longer term follow-up of 9-11 years, the hamstring atrophy was almost 50%! There was also quite a bit of scarring in most patients at the tendon harvest site and the muscle had evidence of dreaded fatty atrophy.
Sugarman is the best in the business so I have no doubt they did everything they could and took every precaution but every patient and surgery is different so who knows why it's not healing but this seems like a common issue for a lot of ACL patients. One big assumption here is that the hamstring issue is on the same side as his repaired ACL. If not, then I'm an idiot and you can rip me.
