The reasons he stated he committed are where I disagree, this is all speculation but I think most of that was probably just natural stuff you say when you pick a place:
1. Fan growing up: He was a PSU fan
2. Passionate fanbase: True; but maybe a little more than he bargained for when he saw it up close
3. Tom & Terry: Don't think anybody is truly picking TnT over the staff at PSU/Ok State and even others at this point
4. Jesus Trained: You can be a Jesus trained guy at Iowa but there are other places that do a lot more of that stuff
5. Spencer Lee: I think this was the actual reason, and picking a school to train with a guy who's going to be a few weight classes below you, and doing a lot of traveling doesn't seem like a it should win when you really think about it.
2/5 were objectively true here. Couple this with a potential issue (I don't think the money disappeared for him, but maybe the people putting the money up weren't so friendly behind closed doors, or were a bit aggressive with Melvin?). All speculation, and hopefully we do get more info.
