3 years seems like enough time to figure out what you have and start to rebuild it, if you think it's necessary? Why, it almost seems prudent to do that! you could go the Benning route and just start giving away anybody connected with the old regime as well. I guess that's another way. Yes, Tallon's fingerprints are all over the team. He was the GM, so I hope that's the case.
The team took the next step this year, and a lot of the credit went to analytics. There was a rash of stories, including
this one and
this one, trumpeting the new direction. There was a post (can't find it now) detailing the changes they made early in the season to their defensive pairings, a decision which was analytics-based.
I don't think anybody has ever called Tallon a cutting-edge guy. He's not a stats guy. It's not hard to see this as the team moving in a new direction and Tallon paying the price.
