When the Pittsburgh Tribune-Review's Mark Kaboly reported that Jarvis Jones had limited participation in the beginning of OTAs due to a "tweeked" hamstring, Steelers Nation took a deep breath. This is the same hamstring Jones "tweeked" during pro day and then re-aggravated at the Steelers' rookie camp.
The concern is whether Jones' hamstring will become a chronic issue. Sure, this may be just an injury that requires Jones to rest during OTAs. However, it could also betray an underlying issue with him, either in his physiological makeup or his training regimen.
Going into camp, LaMarr Woodley currently holds the title of poorly-conditioned linebacker with hamstring issues. The Steelers don't need Jones to inherit it. They brought him in to re-energize an ailing pass rush. He won't help it much lying on the trainer's bench next to Woodley.
Time will tell if this will become a recurring theme for the rookie linebacker.
