People sounding off on Twitter is the bread and butter of sports stars trolling people online.
Arian Foster however isn't just happy having a go at one person, he's chosen the NCAA.
Whilst being asked on twitter by a fan about who he thinks will win the March Madness tournament, he had a fiery reply.
The March Madness NCAA tournament has already started but begins in earnest tomorrow through until Saturday. But who will win it?
Foster says: "Ncaa will win. They'll get billions, players get a trophy."
Now, is this Foster being a little bit bitter about never winning a Heismann trophy? Probably not.
He is intact totally right. Stories are made, dreams are broken and miracles become reality for the March Madness tournament. Which means the NCAA make some big bucks.
So fair play to Foster for speaking his mind and the truth. Although unless he really likes watching American Idol, we're sure he'll be watching the tournament like the rest of us.
