Wasn't pointless. Point is people can talk about a leap all they want, it hasn't happened.
I even like Wilson, but if there was going to be a leap in the defensive performance then it would have happened by now. Plus, people aren't really talking about it, but his recruiting is kind of going downhill. Like we're competing with Purdue for the worst recruiting class as of 2016 right now. He had his big recruiting class, which was defensive based and it still hasn't really shown a leap on the field.
Edit: Also, my bad I read your first comment as "I believe we'll see a big step up by the end of next season", instead of the " By the end of next year there better be results". Just saying it might be in our best interest to actually look for a defensive minded coach.
