Scott Boras -- RIPS JERRY MAGUIRE ... Bromance Is Bad for Business

Jerry Maguire did not complete Scott Boras-- in fact, the super-agent tells TMZ Sports the '96 flick was a blueprint on how NOT to handle a player-agent relationship in the real world.

Boras -- who reps some of the biggest stars in MLB and famously negotiated Alex Rodriguez's $275 million mega deal in 2007 -- was at LAX this weekend when he told us the Tidwell-Maguire bromance in the movie is bad for business.

"The best thing you can do for a player probably is to handle that a little bit differently ... make sure he's more about decision making and what he needs to do and more about his relationship with his loved ones and your relationship is probably more of a professional one."

To quote Bob Sugar ... "It's not 'show friends' -- It's show business."
