Puka Nacua just learned the hard way that even star rookies can’t take shots at NFL refs without paying the price.

The Rookie Phenom says he’s learned his lesson, and Stafford’s backing him to channel that fire the right way. Rams fans—think this will make Puka even hungrier? #Sports #Football #RamsHouse
