re: Will Bo and/or other asst coaches stick around if LSU not buying players?

Yes they aren’t leaving. They know that BK has the big picture in mind and is playing the long game for continued success.
Think about it, soon Congress or whatever powers that be will make players either sign contracts and likely put caps on all this. Then where will Ole Piss, OU, and aTm be when they can’t just over pay for talent because everyone will have to play by the same rules? LSU will be able to show incoming freshmen and high school kids that we built with guys like you that we want to groom you for bigger pay days in the league, not hire one year mercs to come in and take your spot because we paid them a dollar you got a dime.
