I 100% agree with you if the question is simply which would you rather have, but if the question is which was (would be) more depressing, would you still say Kofi leaving? Up until 2-3 weeks ago, I would say that 98% of us would've guessed that Kofi would not be on the team this fall, so while his leaving would be depressing, our expectations were already set that he wouldn't be here (I know I personally have felt surprisingly ambivalent about this saga -- relative to the WTF that was the Miller transfer -- b/c I already didn't think he'd be back) Had he withdrawn from the draft and then entered the portal, I think this would be way worse -- momentary euphoria followed by a huge letdown.
We're also in a very different position than we were in the fall of 2013. There was very little to be optimistic about after Cliffmas other than a vague belief in Groce's charisma and coaching ability. While it would be upsetting to see an Illini legend wearing a different college uniform, we'll be a very good B1G team next year either way and are well positioned for the future.
