🏀 Why this Underdog promo code bonus is perfect for Warriors vs Celtics
The Warriors vs Celtics matchup is one of the most exciting games on the NBA slate if there isn’t a blowout, making it an ideal spot to use the Underdog promo code PICKSWISE04 and lock in $50 in bonuses. Boston is a big favorite in this game, and although this game is expected to feature plenty of scoring and high-impact performances from star players, we may not see a full game from Celtics star Jayson Tatum.
Tatum Under 21.5 points is a great pick to use when claiming this bonus. Underdog’s pick’em format allows you to build entries around player stat projections, making this bonus especially valuable. You can target players like Kristaps Porzingis, Jayson Tatum and Jaylen Brown. Because you’re getting $50 in bonus picks from just a $5 entry after signing up using the Underdog promo code PICKSWISE04, you can spread out your entries and test multiple combinations without significant risk.
This makes the offer particularly valuable for a game with as many elite stat sheet stuffing options as Warriors vs Celtics.
