Apparently it's working. Defensive coordinator Kirby Smart said he's "tackling better."
"I think he put on some good weight over the summer to help protect himself from injuries." Smart said. "The big thing with him has always been health. He's a really fast guy, he's a really sharp guy, very intelligent guy, very instinctual player, but he's been injury-prone. Some of that's been from lack of bulk, some of that's been from poor tackling and poor habits. So he's tried to improve on that, he knows it's an emphasis for him."
Look for Reuben to be a beast this year.
