I think there are many reasons.
1. They are just so beat up.
2. Chemistry issues have creeped in, and Tomlin didn't have experience with that.
3. Loss of leadership allowed #2 to happen and it caught MT off guard.
4. Cohesion has suffered. Team is disjointed.
5. The "young money," immature element is just too negative to team success.
The bad news is I don't think they can fix this by this season. They are going to have to really work hard to fix this in the off season.
