Objectively I have noticed some decay in both judgement and accuracy when he is happy feet'ing. I also don't think he 'feels' the presence of defenders in the backfield when he is mobile like he used to. Ball security is a big negative for us regardless of which facet is in possession.

In the pocket and planted seems to be his sweet spot. When he gets mobile his eyes get real bright like that kid in the yearbook that used to bite everyone. (crazy eyes)
