CBB Parlay Picks Today - Thursday, March 19

We've selected these picks using a combination of Dimers CBB best bets and game predictions to find a combination of value and high probability that gives us the best chance to win our CBB parlay.

CBB Parlay Bet: Illinois to win by 21+ Points

Game: No. 3 Illinois vs. No. 14 Pennsylvania

Time: 9:25 PM ET

The first game in our parlay looks at one of the biggest favorites of the day when Illinois takes on Pennsylvania in their first-round matchup.

The Fighting Illini, one of our model's sleeper picks in the tournament, enter the game as substantial 24.5 point favorites with the Dimers model giving them a 53.0% probability to cover against the Ivy league squad.

Our final projected score is a 90-63 victory in favor of Illinois, giving them a six-point cushion over this alternate line of 21+ points on bet365 alongside their massive 98% win probability.

CBB Parlay Bet: Gonzaga to win by 21+ Points

Game: No. 3 Gonzaga vs. No. 14 Kennesaw State

Time: 10:00 PM ET

Our second leg turns to another big favorite in the final game of the night when Gonzaga takes on Kennesaw State, another 3-seed vs. 14-seed matchup.

Though a slightly tighter spread than the first game, we get the same 53% probability to cover for Gonzaga, with our predicted margin of victory a 23 points in an 88-65 victory for the Bulldogs.

Gonzaga has great depth and a defense that can stop Kennesaw State's three-point shooting, a key factor in their wins and losses this season, and Gonzaga -21.5 even pops up with a little value at its best price according to our model.
