Um who really cares if he's a good interviewer? He only needs to be a good football player.
Such a ridiculous world we live in.
It's like saying, "That chef makes great food but he's obviously an idiot because he can't mix a good margarita".
Also just to add on, who cares if he's highly educated either? He makes a ton of money playing football, if he wants more education then it's up to him.
Just to use a similar analogy to the one above- Do you care if your mechanic has his GED if he's great at fixing your car? I'm guessing not too many people leave their preferred local garage laughing at how dumb the guy who just fixed their car for them is because they themselves couldn't do it(mostly because their masters in sociology means nothing in the world of auto mechanics).
