I think pinning all the blame for the bad start to the season on a single player is asinine. All of these so-called facts are a classic case of extrapolating "correlation" into "causation". I agree that everything here correlates with Bargs' absence, but none of this points to Bargs' absence being the cause of the improvement.
Just because "A AND B" doesn't not mean "A=B". Doesn't work.
I mention this, not because I am an ardent Bargs fan, but because I am not so quick to let the rest of the team off so easy. This is a team sport, and equitable accountability should be demanded by everyone, including the fans.
