"Marrone's not taking any BS, and I think that's the way it should be," Jackson said. "He's handling this with an iron fist, and guys are conforming, enjoying the time and understanding that we need to win some games."
The fresh faces have preached "toughness" from the start, with Coughlin saying in February: "This league can benefit from more of (a tough) attitude. This team can. You've got to play through some things."
Understandably, Coughlin wasn't thrilled with what he inherited. Winning rarely happened under former coach Gus Bradley, as Jacksonville sunk to an inglorious 14-48 mark over the past four seasons.
"Going 3-13 is not acceptable," Jackson said. "And whatever we need to do ... we're going to do what Doug says."
The pieces are there, but they've been there before. It's time for someone -- Coughlin, Marrone, anyone -- to flip the switch.
