Last week, I started an NCAA Tournament series qualifying the key data from my Round-by-Round and Conference Trends articles in the VSiN Bracket Mania Betting Guide, essentially taking the leg work out of the process for readers. Last week’s pieces were for the First Round and the Second Round. Now it’s time for the Sweet 16, featuring four games each on Thursday and Friday. Look for the Elite Eight piece on Saturday morning. Best of luck on the Sweet 16 games.
