i dont know, i believe Steward thinks Cotto is a damaged fighter, he might be in it only for the money.
I was thinking the same thing, but if you watch the Cotto fights Steward commentates, he always picks things Cotto should be doing, especially in the Clottey fight where he was almost sounding thrilled that Cotto adjusted at certain points.
Considering Cotto is still one of the top fighters in the world, it's also an opportunity for Steward to say he's the guy who brought Cotto back up.
