Usually a high ankle sprain takes about 6 weeks to fully heal. This is 6 weeks of staying off of it and going to a lot of therapy. Low ankle sprains can heal up in a a couple of weeks, but Martinez had a high one that has already been aggravated once (a&m game). There is about 6 weeks between that a&m game and the holiday bowl, so I would expect that he would be really close to 100%, if not at 100%. Another thing to think about... Washington (who we're playing) has a horrible rush defense. They have a 5-4 record and have lost to every ranked team except USC this year.
As far as defense goes... for rush defense: Us-#52, them-#103
for passing efficiency: Us-#5, them-#63
for scoring defense: Us-#8, them-#93
for total defense: Us-#10, them-#84

These statistics, and the scores throughout the season tell me that we should be able to score on them through the air and on the ground. Even if Martinez isn't 100% with Helu, Burkhead, Kinnie & Reed, there is no reason we don't win this game
UNLESS our team shows up unfocused, half playing, with lack of motivation. If we fumble, throw interceptions, and have a bunch of penalties, we are sure to beat ourselves.
