I'm not a NFL player so I can't realistically answer that question but, according to Yahoo! Sports Jason Cole, that's the case with Donovan McNabb.
Cole reports that McNabb's camp made it known that he would ponder retirement if traded to the Raiders.
McNabb, who is in the final year of his deal, made this happen by making it clear he wasn't going anywhere else but Washington. When the Buffalo Bills expressed interest - and even were willing to give McNabb a contract extension - he passed on the offer. When the Oakland Raiders sniffed around and showed willingness to trade for the quarterback without an extension, McNabb indicated to the Eagles through his associates that he'd retire.
"He has plenty of money," the source close to McNabb said. "He's not doing anything he doesn't want to do."
This a similar report to the ones that surfaced when Richard Seymour initially didn't show up to Oakland after being traded.
It's getting to the point where, as Chiefs fans, our hatred for the Raiders is dwindling. Instead, I'm feeling a little sorry for them.
