Burton was the only one of those that left the team during the season. McKay probably had some practices in when he announced in Mid-October but he hadn't played a game yet that season. Burton also had to leave when he did so he could start his sit out time in the spring semester of his transfer year and be able to start second semester the following year.
Whole different set of circumstances IMO.
I wish Zeb would stay here and finish out the year, but it's not my decision. He would be very valuable to us as a good teammate and provide good depth at the QB position. I will never hold a grudge against someone for making a personal decision to better their situation, to hold that grudge or be "mad " at someone in these types of situations is very selfish on the part of the fans.
Best of luck to Zeb, thanks for your time as a Cyclone.
