Something I'm noticing that does not help this issue is the camera movement. If you notice the shifting camera during this video, it really exaggerates the sliding feel. I'm not saying sliding isn't there, but the camera does not help.
I agree with the locomotion gaps. It seems speed does not decrease after a juke is made. Locomotion looks good before speed is obtained, but once a runner is in full stride, it appears that the player's feet and ground aren't working together.
