No doubt those guys were good players and coaches, but most of the Heritage DBs will tell you how important Tanis was in their development. Earl Little coached one player, DP has been their DC for the last couple of seasons and doesn’t spend as much time with the DBs as Tanis, and Surtain is in the same spot as DP. If you need more proof of Tanis’ importance for their DBs, McBurrows (who transferred to STA as a junior) had Tanis as a visitor at Michigan games and the other guys you mentioned didn’t go to the Michigan games.
