is the January's hire of Drew Wilson. While not a position coach, you need to recognize his efforts and improvements in 3 categories;
1. Speed - we look a lot faster this year and on par with Pac-12 athletes
2. Strength - we have closed the gap and in some cases been stronger on O-Line and D-line this year
3. Lack of Injuries - This is a big one (so far this year). A number of Pac-12 teams are suffering with major injuries. Outside of Liufau and MacCartney at OLB, we have been pretty much injury-free. A direct correlation to lift techniques, nutrition, conditioning.
You can easily credit Wilson with these player improvements this year. This was a great hire.
