Antonio Brown Holdout Discussion

What do you all think about AB holding out? He has 3 years left on his contract.
The way I see it, he has outperformed his contract greatly and deserves to be paid. We have guys like Randall Cobb making more money than AB. Owners can opt out of NFL contracts anytime the player under performs or gets hurt, so why shouldn't players be able to get paid when they are arguably the best player at his position in the league?
