What makes the injuries so wild is that it was almost exclusively to the same position - point guard.
Robinson... not saying his injury didn't hurt, but he wasn't seen as a primary ball handler. Had Robinson been the only injury, I think things could have shook out differently. You would have still had Butler and Kriisa running the point.
Had Kriisa not gotten injured, then you probably could have sustained the Butler injury. Having Kriisa as your primary point guard with Perry and Chandler playing backup minutes - and even Robinson had his injury not happened - I think the season looks different.
But Kriisa going down, then Butler, then Robinson - that meant you had to rely on Perry and Chandler getting significant point guard minutes. And Oweh was playing the point some and as good as Oweh is, he's not a point guard.
Having one of Butler or Kriisa available all season I think changes things. Had Robinson remained healthy and both Butler and Kriisa go out, that may have changed things - although I'm just not sure how good Robinson would be as a full time point guard.
Also throw in that Carr wasn't 100% healthy all season - although I think he played in every game.
If the three injuries had been to Butler, Robinson, and Williams - I think that maybe changes things. You still have Kriisa to be the primary point guard. You have Brea and Almonor that could step in for Robinson, definitely not the same level as Robinson. You then have Garrison that can step in for Williams, again not saying that's not a step down in production, but you're at least somewhat covered.
But the injuries happened to three (could be) primary ball handlers - that's going to hurt any team because most teams just aren't going to go three or four deep at any one position.
Getting a healthy Butler back for the NCAA tournament is the key to having any thoughts of a deep run in the tournament.
