When I’m handicapping the board, Donovan Mitchell is a standout target for the Over on his consensus 26.5 points line. Mitchell has been an unstoppable scoring force for the Cleveland Cavaliers during this series, racking up an incredible 132 points across the first four games. That breaks down to an average of 33.0 points per game, making him a fantastic anchor for our slips.
On the Detroit Pistons’ side of the court, Tobias Harris is well-positioned against his consensus 18.5 points line. Harris has tallied 78 points so far in the playoffs, yielding a strong 19.5 points per game average. I think his Over is a solid look tonight.
Conversely, we might want to fade Cade Cunningham’s points prop (26.5) and lean toward the Under. Even though he is the primary engine for Detroit, Cunningham has scored 94 points in four games (a 23.5 average), meaning he is currently tracking comfortably below his listed point total for tonight’s contest.
Signing Up with the Underdog Promo Code
To get started and claim your bonus ahead of the Cavaliers vs. Pistons matchup, Underdog promo code WTOP is required during sign-up. The activation process is quick and gets us right into the game:
- Register Your Account: Create your account here using standard personal information.
- Make a Deposit: Once your registration is complete and verified, deposit at least $5 using one of the available secure payment methods.
- Play Your First Entry: Submit a $5 entry on the platform to instantly activate your $50 in bonus entries.
Please note that this offer is exclusively available to new users who meet the minimum age and legal region requirements for their jurisdiction.
Once those bonus entries hit your account, you have two distinct ways to build your slips for the NBA postseason. If you are looking for maximum upside and that big payout, a Standard entry of 2+ picks will trigger the largest multiplier. However, keep in mind that with a Standard entry, every single leg must hit for your slip to win.
If you prefer a bit of a safety net—which is never a bad idea when betting the unpredictable playoffs—your other option is to Flex an entry featuring 3+ picks. While the payout multiplier is slightly lower, a Flex entry ensures you can still receive some winnings even if one leg of your slip is incorrect. Choose the strategy that best fits your play style, and let’s cash some tickets!
