NCAA Coaches want to double tourney size.

Agreed. Doubling the size of the tournament would double the length and cheapen the title.

 

I'd be OK with 4 play-in games for the 4 #16 seeds, but beyond that they should just leave it alone.

 

Actually, doubling the size adds only a single round, it doesn't double the length. In every round half of the teams are eliminated, so 128->64.

 

Someone needs to explain to the NCAA coaches the theory of "if it isn't broke, don't repair it" or the Texan translation "if it isn't broke, dont' fix it".
