It is a measure of his reputation that this question can even be raised. Most S&C coaches are anonymous to all but the close followers of a team, and are not noticed much unless there is a weakness or problem.
In the dim, pre-Barwis, Carr era, the thing above all else that I was most outraged by were comments from opposing players to the effect of "we knew they'd get tired in the 4th quarter" or "they were gassed at the end of the game." We heard this often, even after The Horror, and to hear that from an App St. player was the ultimate indictment of the Gittleson tenure.
So we all were thrilled at Barwis' arrival, and I continue to be glad he is here. And while many trolls make snarky comments about him, we know that our two year losing record isn't really a reflection on any S&C coach, being far more about talent, experience, position coaching, etc. I will caveat the issue with this: I assume it is tough for any fan to really measure how fit and strong a team is, let alone how that translates into winning on the field. The coaches are the only ones with the expertise to do so.
With that aside, do you believe there is evidence to show that Barwis deserves his high profile?
EDIT: to be clear, I'm not asking if he is good, I assume from player comments that he is. I'm asking if he deserves the extra money and reputation that puts him above other good S&C coaches.
