Wayne Gallman saw it often enough at Clemson that he is not at all surprised that his former college quarterback, Deshaun Watson, is lighting things up for the Texans.

“That’s what he does,’’ Gallman said Wednesday after practice. “When you play at something that you love, you have fun with it, and it shouldn’t be anything else other than that. It shouldn’t be hard going out here playing, it should be fun. That’s what we had at Clemson, and that’s what we bring in the NFL.’’

No one is saying Gallman has made anything close to the impact fellow rookie Watson has imprinted on his team in Houston, but at this point, four games into a winless season, the Giants will take anything they can get as far as glimpses of anything positive.

In his NFL debut, at Tampa Bay, Gallman was a bright spot amid the darkness — rushing 11 times for 42 yards, catching a 4-yard touchdown pass and actually making the Giants rushing attack look adequate.

“Wayne’s a young player who plays fast,’’ coach Ben McAdoo said. “I think you saw the speed when he jumped onto the field. He has electricity in his game. He’s a talented, young player. He has a lot to learn, but he’s very, very willing and works hard at it.’’
