I would like another rotation big too, but I think there is a lot of faulty reasoning here.
-We didn't lose to those teams bc they are more physical teams. We lost to them because they are better. Like L says, they executed their game plans better than we executed ours. Vs. UConn, we missed makeable midrange shots and shots at the rim, and vs KU we couldn't stay out of foul trouble.
-You're ignoring the fact that we ourselves ran off the floor teams that were far more physical than us. Houston was an incredibly physical team this season, and we dominated them. The most physical player we've played the last two seasons is Walker Kessler, who finished 3rd in NBA rookie of the year voting this season, and we totally neutralized him. IU and USC were also far bigger teams that we handled. Plus, Duke has been one of the biggest teams in the country the past two years and we've more than held our own.
-Lastly, there is precedence for winning titles with perimeter-oriented teams. Nova won 2 out of 3 recently while playing small ball.
For us to take the next step as a program, we need to get better, not bigger. Getting bigger is one way we might get better, but it's not the only way.
