I don't think it's hindsight bias to criticize the draft. And I don't think it was a terrible first round for them. Mercer, by any measure, was quite a good pick for a back-half first rounder. I wasn't enthused with Muk, but they used him as the equivalent of a 1st round value to add Meier, so no issue there.
I don't think it's hindsight to criticize the Holtz pick though. It was not a good pick and that was my opinion at the time. One-shot scorers, with minimal other + value attributes, are very risky selections. Too many paths to failure IMO. I had Rossi and Perfetti rated far higher than Holtz, and also had Jarvis and Lundel ranked better too. It was a bad pick. Fitz made it worse by mismanaging the asset after the fact too.
