It really is not wrong but being realistic, consider it was his first playoff game for a team with a 29 year drought of road playoff wins, on a field that was nearly impossible to be truly effective, in a game his defense let him go down 14 zero before he even had a chance to blink, 3000 miles from home, on and on. It really should be no surprise he didn't have his best game but what the article doesn't talk about is his moxy and determination or the complete preparation of getting his entire team to believe we will win.
The nice thing about that Washington game is that Wilson will use that performance to motivate himself and in turn the team to be better next week and I for one believe he will be.
