Think Dez Bryant's pumped about hiring Jay Z??
Just two days after inking a deal with the Roc Nation Sports agency, the Dallas Cowboys wide receiver finally announced it to the world by throwing up the official Roc Nation hand signal.
Dez joins a Roc Nation roster that already boasts superstars like Kevin Durant, Victor Cruz, and Robinson Cano ... who just recently signed the dotted line on a $240 million contract.
Ya gotta think Cano's deal was a huge factor in Dez's decision to join Jay Z's team -- 'cause he's a free agent after this season ... and it's clear, #88 is hoping Jay's gonna show him the money.
Throw your diamonds in the air.
