Daryl Katz promises to spend the maximum under the NHL salary cap and help build a new arena if his bid to buy the Oilers is approved. The Edmonton billionaire, in his first public comments since making his third attempt to buy the team, explained his motives in a statement Tuesday. "To be clear, I am committed to building a winning team here in Edmonton and I would play to the salary cap every year to help make sure that happens," the pharmaceutical mogul said in the release.
