If by “approaching” you mean you think Gase is worse than Rhule, I got news for ya.
Gase averaged 6.2 wins per season as a HC, Rhule averages only 5 (and this with the advantage this year of an extra game on the schedule).
Gase had one winning season as a HC, Rhule has none.
Gase had one playoff team as a HC, Rhule has none.
By every objective measure, Rhule is *already* a worse coach than Adam Gase.
