The five-time MVP said hes always been driven to improve, a quality thats even more essential at age 38, and thats why he met with Alabama coach Nick Saban a couple of weeks ago. Saban shared defensive tips with Manning, who gave him pointers on the hurry-up offence that has befuddled the Crimson Tide. Saban said Denver offensive co-ordinator Adam Gase also visited his staff that week. NFL rules prohibit players and their coaches from meeting before the start of off-season workout programs, and thats why the NFL said it would look into the matter. Following the Broncos first organized workout Monday, however, Manning insisted that he and Gase didnt break any rules because they didnt meet with each other in Tuscaloosa. "Yeah, that didnt happen. We know what the rules were. Like I said, I was there on an independent project, and Adam was as well," Manning said. Saban has also said that Manning and Gase didnt meet with his coaches at the same time. Gase and Saban go way back: Gase got his start in coaching under Saban in the 1990s at Michigan State and followed him to LSU as a graduate assistant. As for fans from the quarterbacks alma mater who might be upset that he met with a rival coach from another SEC team, Manning said he still bleeds orange. "Obviously, I have been to Tennessee doing the same thing for the past 16 years. Ill do that, going to make it 17 years in a row, going back to Knoxville. Hopefully that covers me as far as being loyal to my university," Manning said. "Most of the other places, I go just one time. So Ive got 17 years at one place, so I think its pretty clear where my loyalties lie. "The projects I did this year were to help the Denver Broncos and to help me. That still is what my job is, to make myself a better player." The NFL rule prohibiting players and coaches from meeting before the start of the volunntary off-season workouts, the first two weeks of which are limited to strength and conditioning work and rehabilitation, were installed with the latest collective bargaining agreement a few years ago.dddddddddddd. Its designed to prevent players from feeling pressured to meet with coaching staffs during whats supposed to be their free time in the off-season. Players and coaches often get together in casual settings and NFL coaches often meet with college coaches. Mannings appetite for improvement is what led to his trip this off-season to Alabama. He also visited Oklahoma and Oklahoma State. "Theres different things that Ive done throughout my career in the off-season that Ive sought out someone to talk to, something to study to try to make myself a better quarterback," he said. "I believe in this league you either get better or you get worse -- you dont stay the same. I know that has gotten a lot of attention, but that is something Ive done throughout my career. "I certainly know the rules, but I know theres no rule that says a player cant get better -- at least I havent read that one. Thats what I was trying to do and I believe that is important, especially as you get older, in the off-season to try to seek out some things to try to make yourself a better player." Seeing the leagues only five-time MVP trying to improve impressed new defensive end DeMarcus Ware, who was lured to Denver by a three-year, $30 million offer from general manager John Elway and the chance to play with Manning, whos intent on getting back to the Super Bowl this season following the Broncos 43-8 loss to Seattle in February. "Sometimes it doesnt matter about accolades, it doesnt matter if you were MVP or not, its what can I do to really get better for next season?" Ware said. "Peytons one of those types of guys that puts in that effort, not just on the field but off the field, trying to figure out, What can I do to get better? Because he has a bad taste in his mouth from the last season and he doesnt want it to happen again." ' ' '
