Well, one reason I don't think some Redskins received second contracts with the team is because the coaches were not putting some of them in position to maximize their talent and results, especially on defense.
Trent Murphy and Preston Smith were cases 1 and 1A.
Then you can also look to the Chiefs who were able to win the Super Bowl with two Redskins draft picks, Breeland and Fuller, in the lineup.
To me trading a 24 year old cornerback who was just coming into his own (Fuller) as part of a deal for a 35 year old qb like Alex Smith was something only a front office that was desperate would do, which they were after fumbling the Kirk Cousins situation.
That's two #2 picks, a #3 pick and a #4 pick that we allowed to walk out the door for little return.
It's not that this team had no talent, the front office just let it get up and walk away.
