Clip of Mosely saying he sparred Frampton and at the time Frampton was about the same size at him. I guess hes exaggerating a touch? https://www.youtube.com/watch?v=fuGj0DfshxI
He's a tiny man. Below average height for 122, doesn't have broad shoulders, especially has a stumpy reach. He doesn't have the body to put on 20 lbs in his worst shape. I rate him very highly and think he beat LSC easily, but I think Selby and Russell's size advantages would make for much more challenging tasks. Shane was obviously praising Frampton for being good enough to spar with welterweights.
