Also, one more thing to add before setting your lineup this week, aside from what I said above. When Edge went down a few years ago, he still practiced that week leading into the game, eventhough after Indy said they knew he wasn't starting.
So what does this mean? If you see a report Marvin practiced, still be wary of him starting. Indy is notorious for playing "their hand close to the vest."
I have Harrison, traded Wayne ago two weeks ago (Whoops), and just picked up Walters.
As a final note, look at Indy's last few games. Even with Harrison in, Manning was moving the ball all over. Every week it was whomever got the TDs that seemed to do well, and it always changed.
