The joy of doing these bracket updates in such short proximity to each other (twice a week until Selection Sunday—strap in, folks) is seeing the incremental changes that happen from day-to-day. NC State loses to Boston College, Arkansas loses yet again (to a bubble rival, no less), Louisville took a week off (but the Cards’ opponents didn’t)...all of these results roll up into a similar (but different) bracket just a few days later.
That’s balanced by a need to look fresh at every résumé—if you merely make adjustments to the prior S-Curve, you can miss things (like a win falling from Quad 1 to Quad 2), and we try to avoid missing such key changes.
