I mean to reply to this one earlier. If you go to the game, one alternative you might want to consider is Metro C (formerly Metro Green) Line. You can get off at the Hawthorne/Lennox Station and catch a free shuttle bus to and from the stadium on game days. When I saw the Rams play the Bills earlier I drove to the closest Metro C Line station to me and then took the train to the Hawthorne/Lennox Station. I preferred that to driving all the way to the stadium. The traffic around there is very bad on game days, and the parking is outrageous. Time-wise it was probably a wash, but hassle-wise I came out much better too.
