Kevin Jarvis stayed on the practice field for extra work Thursday, then trotted off with offensive quality control coach Steve Oliver, deep in conversation about what improvements he could implement for the next day.
A former Michigan State football offensive lineman who signed with the Detroit Lions as an undrafted free agent, Jarvis is fixated on daily improvement in his first NFL training camp. He'll gladly spend extra minutes — even after the longest practice the Lions have run this preseason — working on his technique and learning.
"I'm just trying to do anything I can to stay here," Jarvis said.
