New coaching metric offers praise for Vrabel, concerns over Callahan

A new metric aimed at grading coaches’ performance offers some long-term appreciation for former Titans coach Mike Vrabel while forecasting concern over current Titans coach Brian Callahan.

Sports Info Solutions, a sports data website, recently debuted an “expected wins stat,” measuring how many games a team should have won based on measurables from every play of every game. The formula uses a summed version of each player on a roster’s “wins above replacement,” which SIS takes from its Total Points player value stats.
