There's been a shadow hanging over the ' OTAs, as first-round pick wide receiver has been on and off the practice field ever since he first put on a helmet for rookie Ray Allen Jersey minicamp. It appeared to have something to do with conditioning, but was it that he was out of shape? Did he have allergies, or something that affected his breathing? It's a question every reporter wanted to know the answer to.When Burks spoke with reporters just a week ago, he was rather mum on the subject. When asked about his conditioning level, he responded Oscar Robertson Jersey saying it "differs every now and then." Burks had also been seen with an inhaler, but said he would keep his reasoning behind it "in house." The rookie even told reporters to ask head coach Mike Vrabel if they wanted more details, but Vrabel declined comment when asked.Tuesday, the NFL world finally got some clarity as to what the former Arkansas star was going through, and it came via wide receivers coach Rob Moore."Some of those things that happened were kind of out of his control," Moore said, via. "The kid's got asthma. Those things happen. But he understands what the expectations are, but I think at the end of the day, it's really him getting himself immersed in the D.J. Augustin Jersey culture of how we do things here, how we play here, which is different from every player that comes in here from college because we ask these guys to do things that a lot of teams don't ask them to do. "I'm excited about Treylon and what he's going to be able to bring to this football team. He just has to get himself healthy and be able to show everybody Jrue Holiday Jersey out here on the field what he's capable of."Burks is hardly the first profe sional athlete or NFL player for that matter to deal with asthma, but the way this i sue has been handled by the franchise turned this into arguably the top headline of Titans OTAs. Vrabel said Tuesday that the Titans were aware of his asthma before the draft. It's something that will continue to be discu sed, as Burks also mi sed Tuesday's practice se sion, with Vrabel simply saying that he was "unavailable." There's also plenty of pre sure on the young Burks, as he was drafted moments after Tenne see shipped to the . If the Titans want to repeat as the No. 1 seed in the AFC or AFC South champions, Burks will have Ersan Ilyasova Jersey to be an immediate contributor.
