Miguel Cotto, with son Miguel Cotto III in tow, was in the house at Madison Square Garden on Sunday to link up with Carmelo Anthony before the Knicks administered a 121-100 blowout of the Pistons. Cotto will be center stage at MSG again this Saturday when he challenges Austin Trout for the WBA light middleweight title live on Showtime. History is on Cotto side; since his debut at MSG in 2001, Cotto is a perfect 9-0 in fights there, most recently a revenge TKO of hated rival Antonio Margarito last December. Too bad Melo couldn’t bring Cotto to Barclays last night to lay a good left hook on Jerry Stackhouse.
