At 1:10 p.m. Tuesday, Gus Bradley started a new era of Jaguars football by yelling, “All right, let’s go, roll, set,’’ as the players took the field for his first practice as a head coach. After a practice that lasted almost two hours, Bradley was upbeat with the way the players have embraced his program on the first day of veteran minicamp. “It was just what I envisioned. High tempo, guys busting their tail, guys running from drill to drill, the tempo was high and we pushed them just like we had envisioned so I was very pleased with that. This was definitely something to build on,’’ he said. Veteran tight end Marcedes Lewis addressed the team after practice and said, “Going into my eighth year, I’ve never been a part of anything like this as far as the first day of minicamp. They threw everything at us and we came out with a great attitude and we executed.’’ He added, “Gus talked about they’re going to apply pressure in practice so the games are easy. We got a clean slate. Everything that happened last year is a blur now. All we can control is our future.’’ It was also the first day of the quarterback competition between Blaine Gabbert and Chad Henne. They are likely to be joined by a third quarterback at some point in the future, possibly a draft choice. It was the first time Gabbert has thrown in a team situation since he was lost for the season in the 10th game last year. “He did a good job. We threw a lot at him,’’ Bradley said.
