Lamar Jackson jostled slightly in his seat, tugging at the sleeves of the black jacket he wore to the Atlantic Coast Conference media days. He wanted to not just talk about but also show the physical transformation he’s made this offseason — going from last season’s playing weight of 198 pounds to, now, 208. “Suit feels a little tight,” Jackson saud, smiling. “But I feel good. I can still move.” And that’s key, of course, for the dual-threat quarterback and reigning Heisman Trophy winner who captivated the nation with his speed and affinity for scoring touchdowns. He’ll still be quick, he’ll still be shifty — but he’ll likely be a bit harder for defenders to bring down. Oh, and he’s going to be under center significantly more this year, too. At first, it’s a bit of a head-scratcher. Why take a player who did things that hadn't been seen in college football since Michael Vick out of the shotgun? Why mess with a system that worked so well it earned Jackson college football’s greatest individual honor? “We felt like there are some things in our offense that we weren't able to execute at times last year or the year before that,” Louisville coach Bobby Petrino said. “So, we wanted to get better in our overall scheme of offense. I also feel like we need to take some pressure off of him where he doesn't need to make a decision every single play out there, whether it's throwing the ball and making the right decision, or handing it off or keeping it or pitching it. There are some really good run schemes that you can do and some play action schemes you can do with the quarterback underneath the center. “It's also to help him prepare for the next level.” The 6-3 quarterback wants to show he’s more than just a running quarterback who dashed and dazzled his way to the highlight reel. He wants to prove he can be a pocket passer, too, with the right footwork, making the right reads. “He took a lot of pride out on the practice field, understanding the coverages, what the safeties are doing and going through his progression,” Petrino said. “He also worked real hard on his footwork, making sure he gets set, gets his back leg under his hip, and when he does that and stands tall, he's a very, very accurate thrower.”
