During the final day of the Pittsburgh Steelers second OTA session of the 2013 season, the team was treated to a sight that put smiles on all of their faces, as rehabbing tight end Heath Miller was spotted doing 100-yard sprints on the field next them.

Steelers quarterback Ben Roethlisberger explained what they observed after Thursday\’s practice when he was a guest on 93.7 The Fan.

“We saw Heath Miller running today on the field next to our practice and everybody kind of just had this big smile on their face,” said Roethlisberger. Coach Kirby (Wilson) said, \’Ben, look over there\’, and we saw Heath like running a 100-yard sprint and looking good running. And It makes you feel all warm and bubbly inside; it just was great.”

Roethlisberger went on to explain why he believes Miller, who is now just over five months removed from his knee surgery, will come back better than he was prior to his injury taking place.

“Heath\’s game was not predicated on speed and quickness,” said Roethlisberger. “Heath was all about technique, and he was about strength. It\’s never good to have a surgery like he had, but it\’s not going to be to me as devastating, I don\’t think, because as hard of a worker as he is, when he comes back, I think Heath is going to come back stronger and better than ever.”

While Miller refused to put a timetable on his recovery when he talked to the media last week, Roethlisberger has not been shy about predicting his tight end will be ready for the season opener. With over three months to go until the start of the season, Miller certainly appears to be on track – a 100-yard track at that.
