As if the men's USA Men's hockey team wasn't under enough pressure ... now a major porn company is making things worse -- by offering them 10 YEARS of free porn if they win gold.

... and not just any porn, HD PORN!!!

TMZ Sports has learned ... Brazzers says each player on the squad will get a month-long membership to the hardcore porn site if they beat Canada today ... and if they win the gold-medal game -- they'll get a full 10-year smut pass!

That's a whooooole lotta smut.
