I don't know how else to interpret the move to release Edwards at this point, when he is not contributing nor adding to the detriment of the team. He was kept but has not produced. Typically, the last receiver on the depth chart produces very little during the games, if they are even active.
If it was to send a message to the so called "safe" guys, or so they think, that it's time to get serious, then I would like to thank Armanti now for being the sacrificial lamb that could get everyone else's attention. From an extremely optimistic point of view, we really are at the critical point and the season is not lost. But it's as close as it can be.
