The Patriots are one week into the Cam Newton era and Dave Portnoy is ready to schedule the Super Bowl parade ... with the Barstool Sports founder telling TMZ Sports their new QB is a straight-up MONSTER!!!
Oh, and Tom Brady?? Portnoy says that dude's looking like an "antique!!!"
We caught up with El Pres out in NYC shortly after New England's 21-11 win over the Miami Dolphins on Sunday ... and he said Cam's performance was great from start to finish -- beginning with his can't-miss pregame outfit.
