Retirement hasn’t softened Sean Avery. The former Ranger and eternal agitator took yet another swipe at Devils great Martin Brodeur — or, Fatso, as Avery once coined him — after Brodeur deemed Avery’s elimination from “Dancing With the Stars” embarrassing. “Woke up beside a #Supermodel to hear news that #Fatso made a comment…..@DancingABC equals Thousands of $ for charity,” Avery, who retired after the 2011-12 season, tweeted Thursday afternoon, though he quickly deleted it.
