He didn't prosper under Parcells in Dallas immediately, was turned loose
Parcells shipped him out because he threw a jersey into Parcell's face and had a little hissy fit. From that day forward Parcells was just waiting to get rid of him and finally did for Quincy Morgan. Then the brainiacs in Dallas let Morgan go so they can sign Peerless Price. What effing buffoons Price is horrible and Morgan showed a little promise last year.
