Mrags, I wonder why you shudder when you hear "re-up".
It was used in the military as the term to "re-enlist" (sign up for 6 more years in the Army or whatever branch).
The re-up concept was quite distasteful to some soldiers because they were not there voluntarily. This was the Vietnam era when the draft was still in effect. I can't imagine why the term "re-up" in a football sense would bug you, but everybody has their buttons.
Personally, I find the expression "I just threw up in my mouth a little" to be pretty foul, but some people like to express themselves that way.
Off topic a bit, but hey, that's life.
