He's drafted a good young core that hopefully will continue to improve. He addressed the organization's lack of centers with hopefully a number 1 and a strong number 3 in Grigs and Girgs. He acquired Hodgson to address the center position and he appears to be panning out. He's started adding some meat to the team to counter their anti-physical neutering.
You're not separating the 6 years from the last couple under Pegula when he didn't have the same restraints. My issue with Darcy is that he hasn't canned Ruff but hopefully it'll happen soon.
The core is only as good as the coaching, and Darcy is responsible for that.
