People I know who are close to the program said that, as often as not, Ty was coaching his coaches as well as the players.
I get it. 2017 was a disaster so I'm not gonna convince anybody that Ty shouldn't bear a good portion of that, but the portion I believe he should bear is that he was willing to come without demanding that he get a real support staff.
Again, I'm not gonna convince you and that it fine, but for me, I know what his goal was and I believe he could've done it. If I were Morpheus, Ty is my Neo.
