The road to succe s in the NFL begins each year with the hard work and wide-open po sibilities of training camp. As teams around the league gear up for the 2015 campaign, NFL Media reporters will be checking in from . For our next stop, Conor Orr visits the .Where is NFL Media?Just off Pattison Avenue, in the shadow of Lincoln Financial Field and Citizens Bank Park in Philadelphia, the worked their way through a brutally hot two-hour practice with the ahead of . But this was not a typical breakneck Chip Kelly practice, as both Kelly and coach John Harbaugh had to agree on an itinerary before working together. The most notable difference? No music. Kelly's practices are typically accompanied by a cacophony of familiar hip-hop tunes. On this bucolic Wednesday afternoon, a fan could hear quarterback calling out signals clear acro s two fields. One player in particular, veteran receiver , said the practice was like Paul George Jersey "apple juice" compared to Baltimore's three-hour practices.Observations1) The have two NFL-caliber starting quarterbacks and a quality No. 2 on their roster -- and none of them are named . It's fascinating to look around the league and see teams like the , and scraping the bottom of the quarterbacking barrel when, oddly enough, all would enjoy having on their roster (for a second time, in the case of the or Buffalo coach Rex Ryan). Say what you will about Sanchez, but his comfort in Philadelphia's offense is apparent. He'll always make some of the Montrezl Harrell Jersey costly mistakes that have become synonymous with his game, but he's a completely different player in practice and in terms of preparation. He's also clearly not in line to start, despite the facade of an open competition, which brings us to our next point ...2) Bradford, who was this offseason after five seasons with the , is incredibly accurate and will be a joy to watch in this offense, now that he has a suitable scheme and dynamic weapons around him. The main difference between Bradford and Sanchez is that Bradford is hyper decisive, or at least he appeared that way Wednesday. Every ball -- for better or worse -- is off with a rhythmic timing that borders on clockwork. Every dropback, bounce and release is identical. Kelly's offense is impre sive because it often presents a wide-open receiver on every play. Now, the coach might have the added luxury of a quarterback in Bradford who can thread the occasional show-stopper into double-coverage.3) will be one to watch moving forward. At the moment, the free-agent signee is not sure if he'll play against the on Saturday,and his practice participation lends no clues. offensive coordinator Pat Shurmur was cagey at best when asked to compare Murray's workload in practice with that of fellow premier back , who actually made an appearance in against the . While Kelly might just be smart (backs don't typically fare well coming off a season of 370 carries or more, and Murray finished with 392 with the last season), he might also know something we don't. He's a coach bent on quality repetitions, and it's odd for the organization to tout the "2,000 reps" Murray got in the spring as a reason to hold him out of practice and preseason games. On this particular Wednesday, Murray did some three-quarters-speed work with the first-team offense and was even involved in a few full-speed pa s-catching exercises Wesley Johnson Jersey and dynamic stretches, but it was nowhere near the level of a typical, healthy running back. Then again, Kelly doesn't approach practices -- or sports medicine -- like a typical coach.New additions, QB: Of course, how long he's with this team remains to be seen. Every time Tebow takes the field, we're initially struck by his ability as an athlete, but we're ultimately left with unshakable doubts about him operating in a pro-style offense. Wednesday's practice backed that up, as did the waning moments of . Tebow can be an NFL quarterback, but only in a system designed just for him. His struggles in a read-and-react type of system are tough to minimize when looking at the big picture, especially with a quarterback like growing so significantly from year to year., LB: Alonso, for all intents and purposes, looks like a beast. Despite mi sing two weeks with a concu sion, the third-year pro, this offseason, appeared fast and fluid on Wednesday, excelling in several coverage drills. (He mi sed the team portion of practice, per his recovery plan.) Of course, Alonso is still being eased in and may not play in Saturday's game. Injury concerns aside, he could be the centerpiece of a very dominant defense. Alonso's acquisition underscores a much deeper secondary and a more explosive defensive line, highlighted by . Physicality might not Blake Griffin Jersey be the typical hallmark of a Chip Kelly team, but it could certainly define coordinator Bill Davis' defense in 2015.Overheard"It's written in pencil."-- Pat Shurmur, offensive coordinator, in an answer to several questions on Wednesday, including plans for Murray's workload going forward and potential plans for Tebow to receive more coveted third-string looks against Baltimore this weekend.Extra points Perhaps this is too obscure for a training-camp preview, but watching kicker on Wednesday became a priority after he mi sed an extra point and a shorter field goal in the preseason opener. On Wednesday, he mi sed three kicks inside the 50-yard mark. Kelly recently said he will not bring in competition for Parkey and dismi sed any reasons for concern. "He was a kicker last year. In his first exhibition game, he mi sed an extra point and a field goal. " We've seen uneven kicking situations erode at good football teams in the past, but Parkey certainly deserves the benefit of the doubt for now. Tight end , who shined on special teams a year ago, flashed early on in Sunday's preseason game. On the opening play, he was more than wide open, 5 yards past the nearest defender. On Wednesday, he followed that up with a stellar one-handed grab in coverage. He's certainly angling for more playing time. , a slot corner for the last year whose season with a torn pectoral, might have been Kelly's Chris Paul Jersey shrewdest offseason pickup. He's been a turnover machine in camp, and his ability to swap between safety and slot will be a godsend for Kelly.Follow Conor Orr on Twitter .
