New Buccaneers coach Greg Schiano, who coached Patriots cornerback Devin McCourty at Rutgers, is very confident that his former pupil will regain the form that sent him to the Pro Bowl as a rookie. “He’ll be back. There is no doubt about it,’’ Schiano said. “I didn’t really know he was having a rough patch. I know he got [injured] a little bit. He’s been fortunate that hasn’t happened to him very much in his career. I know that’s one thing, if he didn’t play at the level he did before, that probably had something to do with it.’’
