Jaguars defensive end Jeremy Mincey has a simple criteria for judging rookie offensive tackle Luke Joeckel. “I haven’t seen him knocked on his butt yet” Mincey said. “That’s a big plus. I usually like to get a hold of the young rooks and welcome them to the league but he’s been holding his own.” Joeckel has managed to avoid looking like a rookie through his first week of training camp. The second-overall pick in April’s draft has impressed the coaching staff and his teammates with his early adjustment to the NFL. “Really steady and that’s a good feeling to have a guy like that out there” Jaguars coach Gus Bradley said. “He’s still learning the speed of the game and the challenges we face every day. … When we watch him we feel his progress has been really really good.” The Jaguars need Joeckel to become a force at the right tackle spot to help boost an offense that struggled last season under coach Mike Mularkey. The team finished 30th in rushing and scoring a season ago going a franchise-worst 2-14. Jaguars running back Maurice Jones-Drew knows Joeckel is performing well because he isn’t hearing much around him during practice. “He doesn’t make a lot of mistakes which is key” Jones-Drew said. “You don’t see him because he doesn’t make mistakes. He doesn’t get yelled at. He’s real quiet. He’s a perfect fit for our team. He’s a draft pick that we plugged in and immediately everyone on our offense got better.” The 6-foot-6 306-pound Joeckel does seem to be figuring out his assignments in offensive coordinator Jedd Fisch’s system. Coaches haven’t had to disrupt the flow of a drill to give Joeckel extra instruction. Joeckel started all 39 games of his career at Texas A&M at left tackle but will be on the opposite side of the line as a rookie. “I feel real good with the scheme” Joeckel said. “We still have time left in camp and then the preseason games for me to get 100-percent comfortable at the right tackle position and with the offense.”
