JACKSONVILLE, Fla. – Minshew Mania 2.0 might be better than the original.Gardner Minshew threw three touchdown passes, including a 22-yarder to Keelan Cole in the fourth quarter, and Jacksonville opened the season by stunning Indianapolis 27-20 and spoiling Philip Rivers' debut with the Colts.Not bad for a team that was supposedly giving up on the season before it even played a down.“We're going to do our best to make sure we're worth watching,” Minshew said.The Jaguars entered Week 1 as the NFL’s biggest home underdogs, with talk of tanking being the most prevalent preseason topic surrounding the revamped team.
