Correct but bud is the biggest name and high profile fight, and biggest payout fight left for him. Age is a factor as well, if he fights any of those names it'll likely be that send off fight I mentioned earlier and he'll be hanging it up.
Opting out of this rematch likely means leaving double digit M's on the table, he has no reason not to fight Bud again unless he's trying to preserve his physical health for after retirement.
