sports iq is mostly subconscious. they just "know" where the play is going. int iq is your conscious reasoning abilities.
the exception might be nfl qbs and linebackers but idk. the goat qb was just average on his wonderlic, though he was a lock for the top 2 that year, possibly the easy favorite for first overall so he could have not cared while taking it: while intelligent guys like Colin Kaepernick and Ryan Fitzpatrick are mediocre to terrible.
but there are also questions whether iq is a good measure of conscious reasoning ability, iq also has a strong coorelation to socioeconomic class, esp. older tests which have questions that carry non universal assumptions (sake is to rice what grapes are to:?)
