I bolded your sentence above, because I think it is very true of Will. On the other hand, Will isn't at a point where he can look at this totally through Zach's eyes, and I think he'd have to do that to factor in the 'love'. I think all that Will sees is Wally and Clara exerting control, and that must frustrate him well beyond what he's expressing here.
If you think about it, Zach is used to making sacrifices to get what he wants. He's probably had to do that for most of his life, and he's definitely had to do that for football. That's a big part of being an athlete. Will, on the other hand, has only done that with some of his more dramatic moments, but even then, it has been more of a forced thing than a voluntary trade-off.
