For reference, at last bids, Port didn't want to give up more than a third-round pick for Jordan Russell last year, even with him being uncontracted and shouting his intention to move back to SA.
Needless to say McMahon has shown a lot more then Russell, so it might be a poor example.
Either way, I think McMahon is a very specific sort of player. Fast is a word i'd use. You either need this sort of player or you don't. No point in taking him if you don't need his specialties.
