Illinois vs. UConn Odds and Prediction
Take a look at the table below for the most updated college basketball odds for Illinois vs. UConn. These odds come from Fanatics Sportsbook and are subject to change:
| Illinois Odds | ||
|---|---|---|
| Spread | Total | Moneyline |
-2 -110 | 139.5 -110o / -110u | -130 |
| UConn Odds | ||
|---|---|---|
| Spread | Total | Moneyline |
+2 -110 | 139.5 -110o / -110u | +110 |
An Action Network-backed expert Illinois vs. UConn prediction I like is under 139.5 total points (-110). Here is the reason behind this pick, according to expert Sean Paul:
"I'm eyeing the total. It sits at 139.5, and we're looking at a pair of slow-paced teams that don't reach the foul line much. UConn is 306th in free-throw rate, and Illinois is 233rd in the same category. Plus, the Huskies are 319th in adjusted tempo and Illinois is 296th."
Michigan vs. Arizona Odds and Prediction
The most recent Michigan vs. Arizona odds from Fanatics Sportsbook are listed out below for your convenience:
| Michigan Odds | ||
|---|---|---|
| Spread | Total | Moneyline |
-1.5 -110 | 157.5 -110o / -110u | -120 |
| Arizona Odds | ||
|---|---|---|
| Spread | Total | Moneyline |
+1.5 -110 | 157.5 -110o / -110u | +100 |
Here is why Action Network expert Ryan Minion is behind a Michigan vs. Arizona prediction of Michigan moneyline (-125) today:
"I think Dusty May’s bunch has the experience, offensive versatility and defensive prowess you look for in a national champion. While it appears most are siding with Arizona, I favor the Wolverines and believe that Michigan will go on to cut down the nets for its first national title in nearly 40 years."
