Eric Fisher: 'I'm in the best shape I've ever been in my life'

Kansas City's top pick of 2013 has yet to deliver on his lofty draft slot.

But this season could be the one that Eric Fisher finally becomes the Chiefs' dominant left tackle.

"Honestly, I cut like 20, 30 pounds of body fat," Fisher said. "I'm feeling really good."

And that's good news for the Chiefs, whose only returning starter on the offensive line is Fisher. 

The Central Michigan product said he struggled to stay in shape in 2014. He went under the knife before last season started and couldn't lift weights to maintain his weight. Then, when the season started, he packed on the pounds.

How'd he get back in shape this offseason? By stepping in the boxing ring.

"I've really never boxed before," Fisher said, "but I know my punch is one of the things I really needed to develop this offseason."

He added: "I couldn't believe the workout you can get from boxing -- the hand work and the hand quickness. I really think that brought me a long way."
