Seattle Seahawks RB -- I'd Stop Listening to Future ... If Russell Wilson Asked (VIDEO)

Now, THIS is dedication!!!

Seattle Seahawks rookie running back Alex Collins says he's so committed to the team, he'd even give up listening to Future's music ... if that's what his QB wanted.

It's a big deal ... 'cause Future's dope. Everyone knows that.

But everyone also knows Russell Wilson's got some issues with the guy (since he's engaged to Future's baby mama) ... putting Collins (and the rest of the Seahawks who like rap) in a tough spot.

Alex says it's a no-brainer -- his QB comes first.

There's more ... we also asked Alex if he would consider cutting his dreadlocks to avoid comparisons to Marshawn Lynch. But that's where the RB draws the line.

Meantime, check out his highlights ... dude's a monster.
