Allegedly... http://outkickthecoverage.com/five-star-recruit-landon-collins-mom-alleges-nick-saban-promised-job-to-recruits-girlfriend.php You might recall Collins's mom looked pissed when he announced for Bama.
I might remind you that he also promised a job for a greyshirt recruit while he waited until next year to sign because there was no room, and rehab his knee.
I can't believe the mom would get pissed because her son chose a different school than what she liked. It's stupid. Both are top notch football schools and he's getting a free education at both places. Who cares?
As I see it, there are two divergent possibilities: 1) She is, as you said, pissed because the choice of school is not the one she is a fan of and would rather he pick the home state team. 2)She is disappointed that despite her best efforts, she raised a son that was bribed into making a choice, rather than making one like a man. Probably number 1, but you never know.
I don't know that I'd call it bribery. People make decisions all the time based on how they affect a significant other.
personally i think lsu offered her money to have her kid sign with them. nothing else explains that sort of reaction.
