The most improved players this spring on offense, in coach Scott Linehan’s estimation, might come as a surprise to some: tight end Joe Klopfenstein and running back Antonio Pittman. "Both had to adjust to really tough roles last year," Linehan said. "Antonio coming off being released by the team that drafted him and then coming in here and not knowing the offense. And then Joe, he started as a rookie, and then got moved out of a starting spot. It really wasn’t anything he did. We just picked up a guy (Randy McMichael) that we felt that we were going to play in front of him. It was a tough situation. But Joe has had a great offseason."
