If the Seahawks got offers for Edwards, then it's a shame they didn't move him.
I don't get this move. Edwards has made tough catches, and has been under-utilized. At least for me I've found him to have been a pleasant surprise this season. He was signed here as Sidney Rice insurance, and for a minute in the Chicago game, it looked like Rice might leave soldier field in an ambulance. He didn't, but it was a reminder of how quickly things change with injuries.
Maybe Edwards got hurt. Maybe the FO badly needed a roster spot and he was the most expendable. Maybe they wanted an excuse to increase Kearse's rep count (I hope so). Maybe they wanted to save an extra $200k (Edwards' remaining salary for 2012) to add to next year's cap (it's looking very tight so every bit helps). Or maybe they didn't like him anymore (that would be the part I couldn't understand), especially since they passed on the chance to trade him not even a month ago.
As far as Rob's theory about Twitter, I see no evidence to back that up, but I do think that PC/JS are capable of cutting a backup over something like that. They cut Lendale White in a heartbeat for not having a good attitude, and the Curry trade was fast tracked after he made some moronic comments on twitter regarding his benching.
