The Oakland Raiders are off to a disappointing 1-5 start, and some disgruntled fans have already had enough of head coach Jon Gruden - whom owner Mark Davis signed a 10-year contract worth $100 million.

Some Raider fans have already given up on the Gruden experiment, launching IsGrudenGoneYet.com. The website tracks how much Gruden "has made" since visitors arrived to the site, how much he's made since signing the contract and how much he's owed. There's also a countdown clocks - including years, weeks, days, hours, minutes and seconds for when his contract expires.

Unfortunately for Raiders fans, there's a long way to go before Gruden's contract runs up. And for starters, who's to say that Davis won't give him a contract extension down the road? And who knows, maybe Gruden gets fired before the 10-year pact even expires?

Gruden replaced the fired Jack Del Rio and was brought in for the purposes of rebuilding this team. That's a key reason why he traded away franchise star Khalil Mack to the Chicago Bears in exchange for four draft picks. Rebuilds take time, and Davis is going to be patient, hence the 10-year contract.

Jay Glazer of Fox Sports reported on the weekend that the Raiders are also shopping Pro Bowl wide receiver Amari Cooper and young safety Karl Joseph. If Gruden indeed parts ways with both pieces, he promises to land more draft picks to help out during the rebuilding stage.

Oakland is a flawed team with very few strengths. The pass rush is a mess without Mack, the secondary has been ineffective and the offense isn't getting it done. Many are even questioning if Derek Carr really is the franchise quarterback.

Gruden is probably going to have at least four more years to rebuild this team, and if it's going nowhere, maybe Davis decides to cut ties with him and just pay out the rest of the money. But for now, disgruntled Raider fans will have to watch that clock drift down slowly for another nine years.
