After Solo’s quick start, Illinois went all in for a while on defending him with everything they had. The back up guard Lee (#1) was put in essentially just to face guard him and then a second defender would shade his way coming around screens.
Solo made Illinois change their game plan - taking one of their offensive weapons off the floor for a defensive specialist. That’s when it’s time for other guys to step up.
And from Solo’s perspective - sure, he got some clean looks late once Illinois was playing more straight up that he didn’t convert. And he just has to be ready to knock those down - “ok, you cooled me off for a while, but now I’ll make you pay.”
But he had a big part in the win even despite cooling off.
