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, Ian Rapoport visits the .Where is NFL Media?The are holding training camp at their newly built Levi's Stadium, practicing on the actual game field more than ever to try to build a home-field advantage. And for the coaches, fully renovated and spacious offices are a nice touch.Observations1) The lost one of the winningest coaches in NFL history in Jim Harbaugh this offseason, but there is a breath of fresh air inside the building under new coach Jim Tomsula. Everyone seems a bit happier, but only time will tell if that leads to more wins. At the least, players appear to enjoy their jobs more, compared with feeling like they were in a morgue by the end of last season. Veterans will receive fewer reps in camp, but that's not to say it's a country club. Players were given strict weights to hit when they arrived, and they all hit them. 2) It's time for the draft picks to play. For years, thanks in part to the trade, the seemingly have had endle s draft picks. Scott Stevens Jersey They stockpiled them. Well, losing veterans such as Patrick Willis, Justin Smith, and Anthony Davis to retirement or free agency makes it a nece sity to get those young guys on the field. They already view 2015 first-rounder as someone who belongs. Linebacker will play, and so will linebacker , who has worked his way up. Oh, and it's time to see be the bell cow. The well-known names are gone. But inside the building, they don't believe the talent is. 3) has had, it seems, five different careers, as he's battled off-the-field i sues for the past few years. It's dangerous to say "now he's turning his life around," and the Niners have been cautious with their outside backer. But they have seen a different player. Thanks to a re-worked contract, he'll have to earn every penny. Can Smith return to the form that's made him one of the league's best while staying out of trouble? Time will tell. But his coaches view him as a more serious, hungrier player. They think this is the last they'll have to worry about him. New additionsA lot has been written about the lo s of Justin Smith, but the "Cowboy" on the field last year clearly wasn't the same from his prime -- playing 60 percent of his snaps, with mostly one arm. Thus, replacing him with former stalwart is considered an upgrade. Dockett brings the personality (and then some), but also the playmaking creativity rarely seen in a lineman. That is a net win. Meanwhile, a name that's already impre sing the coaching staff is rookie tight end . They drafted him 117th overall, and they already have . But Bell, the former-college quarterback who is still learning the position, could be the future there. One more name to watch: , a 225-pound safety who'll slide down in the box and cover on third down. Overheard"It looks like he's moving around great." -- Defensive coordinator Eric Mangini, on linebacker . Simple, but important. The lo s of Patrick Willis isn't quite as bad when you consider Bowman -- the Robin to his Batman -- didn't play at all last year. It's like we all forgot how good he is. Nearing 100 percent, Bowman's comeback is almost complete.Extra pointsFollow Ian Rapoport on Twitter . Yushiroh Hirano Jersey
