Logan Thomas-Quicken Loans QB accuracy Challange

I'm watching this QB skills challenge, and Logan seems to be hobbling around like he was injured. He wasn't stepping into his throws and throwing with his shoulders already square to the line of scrimmage before he started his throwing motion. He didn't step into his final throw(which was just to see how far you could throw it) and he still threw in 57 yards.

Does anyone know if he's a little banged up or was he trying to work on something? Just seemed strange to me, didn't know if anyone had any information.

PS sorry for no video, just saw it on TV
