CW and Blum have a vested interest in there being excitement around ISU athletics, particularly football and men's basketball. Of course they're going to be more positive than anything. Blum needs to raise funds so we have a chance at having talented rosters. We need fan engagement and excitement to pay for that. CW benefits from fan excitement by getting more subscriptions, clicks, engagement, etc. It's good for business. These guys are also fans that sincerely want ISU to succeed and will look at the glass half full, at least publicly.
I enjoy their podcasts and a lot of the other material that comes out of CF and Iowa Everywhere. I also form my own opinions and don't rely 100% on what these two guys say. They're talented, connected, and most importantly, Cyclone fans, but what they say doesn't replace what I see with my own two eyes.
