Typically I would never pick a basketball player to win in a combat situation, but Nate is not your average basketball player in that he was never a skinny guy, and had insane athletic ability.
If you are in the nba, you are athetic, but Nate was SUPER athletic and has strong legs which can equate to power.
But, I have to ask, what is the size and weight discrepancy in this fight? Isn't Logan considerably bigger?
Logan's wrestling will help in that he more than likely wont be a bitch when it comes to physical combat. He won't be scared of pain b/c he has wresting experience that has made him comfortable with being uncomfortable, if that makes sense. Plus his wrestling helps determining distance which will help in a boxing fight.
