For what it's worth here's my two cents...
This was an abnormal year in the Sun Belt...the league was really down and as a result, the RPI of anyone playing in it is negatively affected...the result is that the committee looks at the regular season champion of a bad conference which fails to win the conference tournament, and takes them off the board...problem is no coach is aware ahead of time that the conference will be so bad...so the strategy of trying to be the top team over the course of the entire season stays in place...the hope is that the body of work and a good performance in the conference tournament results in credibility and an rpi worthy of consideration...doestn't work for a bad conference...
If I coached in one of the conferences that is a one bid league, I would gear up for the midweek games against good opponents and then put all my marbles on the conference tournament...that strategy is used by teams like Monmouth, Bethune-Cookman, etc.
As for not playing starters midweek...weekend starting pitchers sometimes are utilized on a pitch count or in relief, but the position starters play unless they really need a game off...
We went to seven ncaa regionals when I was there and only once did we go as the conference tournament winner...Back then the Asun was always a multi bid league...some really good teams in that league during that period...
I think that record speaks to the soundness of the strategy...
Mac and his guys should be commended for a great season...anytime you bring home a championship and can put a sign on the fence forever, it's a good thing!
