There's a lot of truth in the article, and also a lot of truth from those on here criticizing it. WM and his staff are easy target now, and they were all in last year which was obviously a dreadful mistake. They fail to address that.
That said, I do think there is some truth with regards to the respective staffs. Muschamp's staff was comprised of great recruiters who were decent at best at coaching and developing. Durkin, for example, was about as good a guy as you could find and I can easily see how recruits and their parents buy into his optimism and energy. But I don't think he was qualified to be a DC, and I don't think we saw much improvements in players from year to year. In most cases, players were who they were, good or bad. If you read the comments from outsiders, McMillan is a perfect example of why you can't just recruit. He's apparently finally come around with the coaching and developing of Shannon.
Robinson is another. Sure the guy could recruit. But VH3 had INts in his first 3 games as a Freshman. Not sure how much coaching--in one fall camp--had to do with that. The same could be said for Fowler. On the other hand, guys like Poole, Maye, Roberson, Watkins, Gorman, Cummings, etc have largely been the same exact player their entire careers here, with little sign of developing. Compare that to what we saw from guys like Haden, Black and Wright under the Meyer and Bedford. One year to the next was like night and day. That's what you should see from your players.
Obviously there is plenty of speculation on the new staff. But it does seem that they're actually taking what they have and making it better. I don't think we ever really saw that under WM.
