imo, a good choice. could be rex's successor.
Whiz would be an excellent OC, and --as noted earlier-- a natural candidate to replace Rex in a year if the ship doesn't get righted enough.
The appeal for him is: (1) He either replaces Rex in a year, or (2) gets himself another HC opportunity elsewhere by turning around our dreadful offense.
Unlike Sporano, he's actually called plays. And pretty well, too.
