Oregon State's strengths include three starting guards who can all shoot very well, quality rebounders that typically win the rebounding battle (+14 per game so far), a commitment to team defense that usually results in the opposing team shooting poorly, and they are an unselfish team with solid passers that produce about 20 assists per game.
UConn has few weaknesses and does most of those same things very well.
All of those OSU strengths combine to produce a team that rarely beats itself, but is certainly susceptible to be being beat when it shoots poorly or faces a team that figures out how to score in its half court offense consistently.
I have watched both UConn and Oregon State play multiple times already this season. Both teams are well-coached and will exploit mismatches over and over again until the opposing team catches on. Hopefully, both teams will be able to avoid each other until the very end. In 2016, UConn eliminated Oregon State in the Final Four to win its most recent national title. Oregon State fans will hope for a different Final Four opponent in April 2020 in one of the two semifinals.
