I hear ya in that SEC competitiveness has been prevalent since the early 1990's.
However, I think that competitiveness is more league-wide and consistent now (and in the region as a result). Of course, my opinion is merely anecdotal.
But, consider that Vandy built their new stadium in 2002, Auburn built their's in 2002, South Carolina in 2009, Ole Miss reno in 2009, Baum reno in the mid to late 2000's, new Alex Box in 2009, Alabama building a new one right now, we now have A&M (blue bell in 2012) and Missouri, Georgia redid their seats a few years ago, and State going to build a new stadium. The arms race that started in the late 90's to mid 2000's is now evening out. All SEC schools "play baseball" and are serious about winning (because it makes money).
Before Smoke was fired in 2006, only LSU and Georgia had won a national title and Alabama and Florida had finished second. Since Smoke was fired, LSU has won one, South Carolina has won two and Vandy has won one. Georgia, Florida, South Carolina and State have finished second.
I "feel" like the average SEC baseball team is better than the average baseball team was 10 years ago so it's now harder to stay "average" or better. Then again, if Cohen does actually have the financial commitment and school support above the "average" SEC team, then I imagine there were be some tough questions to answer at the end of the year. I just don't think you fire him yet but the precedent is there. The seat is really really warm next year.
