Try bellowing in an unhinged manner "we're goin' (no G , fake, phony used car salesman Texas accent) to take the Axe and put in our backs. blah blah blah. As it turns out they did not take the Axe and put it on their backs, but for Saturday it should work.
Also drop the letter G at all times. (runnin, hopin, tryin, playin, throwin, firin' that dadgum A hole Dunbar, ect)
Use the terms, Rose Bowl, Special Forces(some callers and posters actually took the cue from the meathead Brewster and enthusiastically used that term when commenting on Special Teams, does anyone on the board want to confess to using the term Special Forces? in a conversation or post?) tremendous, without question, and repeat yourself a lot and you will have it it covered.
In a pinch try to repeat yourself, lie on the floor at times,and drop all the Gs. If you see some grass, start talking about the Rose Bowl turf in your office. If you are in a real bind and need to impress, talk about how your RB stable of Duwann and some other marginal talent has put he program light years ahead of the likes of 1 star Marion Barber and that head case L Maroney. Light years ahead!!!
At times gin up a "gameface" creating an illusion of focus, and intensity. If you have doubts about your ability to pull it off eat 15 pounds of cheese and bread tonight and the resulting constipated feeling might force you look like coach Tim Brewster in a Method Acting sort of way.
What is the plan for the physical part of the costume?
I'd recommend wearing a headset, folding your arms in front of our chest and looking very constipated. (remember cheese and bread, no prunes) At certain points, randomly lay down on your stomach or yell at the officials. (see Bowling Green tape, 2007, classic Brewster moment that should have told us a lot about Timmy B.)
