I don't really care whether they list him at 160 or 180. When I watch him play, I see a really small back. Dunn and James Brooks were 180 backs, but they didn't seem nearly as light as Devine. Darren Sproles is listed at 180. Devine doesn't appear to be as big (or as good) as Sproles, so I have to believe he bulked up to hit that 180. He'd be back to what is likely his natural weight(160) once the season started. He also looks like an average return man. Having him in your top 20 is a mistake IMO.
He played at 175 for 3 years. he was 170 his Freshman year. I also don't get the "light" comment. He was injured last year, facing 8 or 9 in the box at times and ran between the tackles a good deal. He always fell forward and churned out an extra yard or two with his legs. He has tremendous upper body strength, good lower body push, excellent burst and acceleration, very good lateral quickness, very good vision, and heart. When healthy he
can be better than Sproles.
