At times this year, Illinois has looked like one of the five most dominant teams in all of Division I college basketball. 

Perhaps that’s why Illinois basketball odds have become one of the most popular championship targets at BetMGM beyond the top ring of contenders. 

One key problem, though, is Illinois’ recent history of underperforming in the NCAA Tournament. Brad Underwood arrived in Champaign in 2017 and has gotten the Illini into the NCAA Tournament for six straight years now, yet the program has only one good tournament run to show for it.

Bettors will have to weigh Illinois’ strong metrics and a manageable path through the bracket against the risk of another early exit.
