He was hyped quite a bit before the ToP began. We saw the return of his Ultimate form. It was all set up to give him a chance to shine.
Problem is when the ToP actually came around that went nowhere. I like Gohan and all, but we're too far into the tournament with almost nothing from him except a moment or two of him actually doing something, and that was fighting fodder and nobodies. If he wins this will feel like a poorly set up ending. Hell, 18 winning would feel more appropriate (since she's actually done more than Gohan this arc).
I wanted Gohan to do something this arc but I have no more hope he will. Same goes for 17, who I was also quite hyped for, who has done very little himself (though I think he's still done more than Gohan).
The battle royale tournament style doesn't really work from a storytelling perspective.
