There was a
window, and if you look back in this thread it was the day Charles went to see Dr. Andrews ... (within hours I posted to pickup West on this news). It was widely expected that Ware would be the RB in KC going forward. This site (and others) routinely put him as a top5 or at least top12 RB week to week. You might also recall Ware had a concussion in Indy, the following week and many were still saying he was a no brainer RB1 even after the concussion, as he only missed one game and Charles was gone and West was a scrub. He didn't come back until the following week and was setup with a nice schedule going forward. There was about a 2 week window. It actually came up in a conversation in this thread and I said that he would either dive in value if he missed another game from the concussion, or Ware's value would spike back up if he played. I think you still had a chance to sell then.
The window opportunity wasn't long as you say, but it was there for 2-3 weeks ... I have made trades in smaller windows, like this trade I posted in real time when Booker had just assumed the starting role for C.J. Anderson. The initial hype was very high and Booker was being touted by most sites as a no brainer top5 back for ROS.

Looking back today, it looks like a crazy deal in my favor, but at the time it was a very fair offer and I wasn't even sure I got the better end of the deal. You have to pounce while the iron is hot as they say.
