One of the biggest mysteries entering the 2015 season is the health of Peyton Manning's throwing arm.
The first review from Denver Broncos' training camp, via receiver Demaryius Thomas, is a positive one.
"I know you're not going to believe this, but it seems like he has more zip," Thomas told reporters Thursday, per Mike Klis of 9News in Denver.
Thomas' qualification aside, we'd expect Manning's throws to have more zip now than they did during the stretch run last season, when the quarterback dealt with quad issues and his arm appeared worn down.
The key for the Broncos' season is keeping Manning healthy for more than just the start of the season. Denver plans to utilize a more balanced offensive attack than in the past by leaning on the ground game. Coach Gary Kubiak has also built in more off days for the workaholic Manning to try and keep him fresh.
No team's 2015 fortunes rely more on one appendage than Denver with Manning's right arm.
Thomas' comment is a great note, but we are far from the end of this storyline being pertinent.
