I agree Tonyan has quicker feet than Bakh, which I would expect. Relative to other OTs though, Bakh's footwork is amazingly quick.Tonyan has the quicker feet but Bakh has better hands. IMO
As for hands, well Tonyan and Bakh use their hands for entirely different purposes. Bakh is using his hands to keep a DT in front of him and away from the QB. Tonyan is mostly catching balls. Bakh keeps his hands open while Tonyan does the opposite to bring in the ball.
It's encouraging video for Bakh. He wouldn't be doing that stuff with a swollen knee.
