All we can do is try.
Idk if its a pain in the butt for a coach.
Or an appreciated gesture.

I will include a closing notation:

Skol Mr. Flores!
Rekindler of our Purple People Eater beginnings and cherished football identity.
A reply is not expected, we fans of great defense can only imagine how busy you are. Our point is to offer appreciation & support. Not add burden upon that busy schedule.
