C.J. Spiller's 2013 season was filled with percentages.
It seemed like every week there was another number quantifying his health -- 80 percent healthy, 90 percent a go to start, zero percent chance he'd sit. Sometimes, they couldn't quite put their finger on a number, but there undoubtedly was a figure for that, too.
"Well healthy being 110 percent, I would say no," Marrone told reporters Thursday, via buffalobills.com. "But not unhealthy enough where you would have to report it or say it."
"He worked extremely hard. He practiced well. I think at times you can see when he felt really good," Marrone continued. "And there were times he went on the field and felt great and then all of a sudden, within the first series, something might have happened but he continued to play.
"I think once you get a nagging type of injury and you don't have a full amount of time to really let it heal, I think it's something that could affect you as the season goes on."
Marrone didn't speak on the current state of Spiller's ankle, which was the main cause of his hobbling and wincing last year and the primary reason the 26-year-old failed to break the 1,000-yard mark. He did, however, make note of the team's plague of injuries early on during his rookie season at the helm, saying he hopes to make some adjustments and avoid similar outcomes at the start of this year.
"We went through a lot of adversity, through some injuries," Marrone said. "It's going to be very important for us and our type priority to make sure that our players are healthy going into the season and keeping them healthy during the season.
"We did a much better job at the end of our season then we did in the beginning, so we'll go back, evaluate that and see what we can do to help the players."
