Rob Gronkowski shed the walking boot on his left ankle in time for Tuesday's Super Bowl media day. The tight end sounded optimistic about facing the Giants on Sunday night. "I'm improving every day," Gronkowski said. "The only reason it's getting so blown up is because it's the Super Bowl. It's just like any other injury during any other week." Gronkowski, who suffered a high left ankle sprain in the AFC title game Jan. 22, said he could be anywhere from in perfect health to "2 percent" for the game.
