Couple points here:
1) I think we are a Jones away from being a cup contender. He is the one major missing piece, everything else we as fans would want I'd consider more of a luxury (another winger, better 3C, a top 10 goalie). He'd push everyone down the lineup into their correct places, and having him on the ice for nearly half the game of every game would be huge defensively.
2) I think there's a chance the Oilers could sell themselves to Jones. His brother plays for the team. This is a team with arguably the 2 best players in the entire NHL and in desperate need of a #1 dman. Holland could pitch to him that he'd have to potential to be the Letang to Crosby/Malkin, the Doughty to Kopitar/Carter, the Keith to Kane/Toews- all of whom went on to win 2+ cups. Jones is a top athlete and undoubtably wants to win and there is no core he completes better than the Oilers. Coming to Edmonton would be the kind of move where Jones is eyeing multiple cups rather than just winning some playoffs series in a warm city. Also in terms of personal success getting PP1 minutes with McDrai could get him enough offense to be in the Norris conversation.
Edmonton probably won't be his first choice, but I wouldn't say "no shape or form he stays in Canada". There would be some appeal that I'm sure he and his agent would consider. Even considering his political affliations most America's large cities (the ones with NHL teams) lean pretty heavily left. Only the rural regions are hard right, and they don't have hockey teams, so I wouldn't expect that to be a massive factor in his decision making process.
