No. The photographic memory doesn't make in-game instant action better.
The last thing that I want out of my QB in the heat of the moment is processing
loads of details (i.e. excessively slowing his head down.) Photographic memory
doesn't speed anything but the overall long-term efficiency of learning bulk information.
I'm happy that he can be a filmroom consumption freak which will allow him to
later analyze what he needs out of those sessions, but at the snap of the ball
(and the next count afterwards), I want that heavily detailed "academic analysis"
to go away and be in a fast useful "reactionary mental twitch mode." What you
really need at that point is a generally sped up brain which makes the game dynamics
seem to drop into slo-mo.
I cringed a bit when I heard photographic memory. Game-planning, yes. Lightning
in the pocket, no. (Trust me; I had a near photographic memory myself. Great for
academic tasks; mixed bag in athletics. Seeing just how the basketball was going
to bounce before the other guys' do was WAY handier in just those moments, than
remembering which guys wanted to go to their left. Both brain skills have their use,
but when the ball and the bodies are flying, I want the speeding mind.)
Now this doesn't mean Buchner can't have both. Great retention "student" allowing
intense analysis and strength and weakness analysis on one hand, and lightning fast
animal mind on the other (like Wayne Gretsky had in hockey) but these are not at all
the same talent.
