As I understand it, Jones has explained this directly, which is kind of unique. In addition to his billionaire best friend heading to ND:
- Jones has a vision for how he wants to be used as a TE: not just attached, but also not just spread out.
- ND has SHOWN him that they use their TEs in precisely that way, and have had incredible success doing so.
- UCLA has TALKED a lot about how they plan to use him, but have not shown him. Why? Because they can't. They have no film to back it up.
For that reason, ND caught up with UCLA, but he plans to honor his word and give Mora one more chance to SHOW him. So even if he goes on the trip to UCLA, people are assuming that Mora won't win him over because he can't actually show him + Jones is determined not be talked into anything (as opposed to shown) + Jones has great relationships at ND + he seems to talk as if he is leaning ND.
Add all that up, and people are 95% sure he is going to ND. The 5% that remains represents the fact that he originally chose UCLA, so he obvious likes it, and who knows, kids are fickle and Mora is a silver tongue devil... things could change.
