Seattle Seahawks hero Richard Sherman is all about TALKING TRASH in victory ... and he BLASTED 49ers receiver Michael Crabtree after the NFC Championship in one of the most epic rants of all time!
Sherman -- who broke up Colin Kaepernick's final pass to Crabtree in the last seconds of the game, clinching the W for Seattle -- posted up with Erin Andrews after the victory and WENT OFF.
In what felt like a WWE style rage session, Sherman said ... "When you try me with a sorry receiver like Crabtree, that's the result you gonna get. DON'T YOU EVER TALK ABOUT ME!!"
There's more ... the Ultimate Warrior would be proud.
