I don't think economics would be a limiting factor if someone thought he was a game changer. I don't know that he's made that much of an impact. My rando fan sense of MM's reviews is "seems good enough, but not certain he'd move the needle." which generally doesn't get you a lot of money. We'll see how the 2nd half of Reading's season goes. If they start winning some games and MM bangs in a few headers here and there, who knows.
