NFL's James Bradberry Playing For Massive Payday, 'It Helps Me Play Better'

NFL breakout star James Bradberry has been balling OUT OF HIS MIND this season ... and he's telling TMZ Sports his biggest motivation for putting in all that extra work -- getting a FAT new contract!!!

The 26-year-old Carolina Panthers cornerback is widely considered one of the biggest bargains this season ... considering he's still on his rookie contract (4 years, $3.69 million) and has racked up 3 INTs and 30 tackles.

Yeah ... he's a beast.

We spoke with Bradberry about going HAM during his contract year ... and he admits it's given him some extra oomph when he takes the field.

“I’d be lying if I said no," Bradberry tells us. "Definitely it’s always on my mind. And, you know, it just helps me play better. And, if I play good then the team does well. It helps on both ends."

And, what's really gonna make you root for this guy??? How he's gonna spend his money when he inks his new deal.

“The number one goal for me is to retire my mom. You know, my mom she’s worked hard. She’s pretty much a single parent for me and my sister. She’s taking care of my grandmother right now as well. So, if I can retire her, that’s my number one goal right now."

So, let's go Panthers ... PAY THIS MAN ALL THE MONEY!!!!
