NFL's Richard Sherman -- I HOOK MY FAMILY UP ... $2 Mil Home, Plane Tix & Super Bowl Ring!

Richard Sherman is all about sharing the wealth -- just ask his parents ... who tell TMZ Sports the Seattle Seahawks superstar has draped them in riches ... including a $2 MILLION HOME!!!

We ran into Beverly and Kevin Sherman on their way to Seattle Sunday -- when we noticed the MASSIVE ring on Kev's finger.

The couple proceed to tell us that Richard not only lets him wear his Super Bowl ring -- he bought them a sick mansion and pays to fly them out to every home game!

Check out this clip -- Richard might be the greatest son of all time.
