New Orleans Saints running back Alvin Kamara (41) bulls his way into the end zone for a touchdown against Carolina Panthers during the second half of an NFL Wild Card Playoff game in New Orleans, La. Sunday, Jan. 7, 2018. The Saints won 31-26.

Alvin Kamara got almost everything he could want out of his rookie season. 

The Offensive Rookie of the Year trophy was only a part of it. Kamara emerged as a bona fide star, an electric playmaker with an oversized personality that has taken him to the Super Bowl, the NBA's All-Star Weekend, Fashion Week and the other trappings that come with being one of the NFL's up-and-coming stars. 

And yet Kamara still feels like he's not sure he's arrived, at least in everyone's eyes. 

"I feel like people still don't believe in it," Kamara said at the Saints Hall of Fame Celebrity Golf Classic on Monday. "You've got to prove yourself every time you step on the field."

Kamara inspired belief in plenty of people last season. Originally drafted to play a pass-catching role, Kamara made Adrian Peterson expendable, averaged 6.1 yards per carry and 10.2 yards per catch, scored 14 touchdowns and produced a weekly highlight reel of clips that rivaled anybody's in the NFL.

According to Kamara, he didn't watch any of those highlights until a week or so ago. 

"Year two, I'm trying to do more than I did in year one," Kamara said. 

Accomplishing more will be tough for a player who finished sixth in the NFL in yards from scrimmage, led the league in yards per carry and caught more passes than any running back other than Le'Veon Bell. 

Bell, of course, has the backfield to himself. Kamara shares the workload with veteran Mark Ingram, a back-to-back 1,000-yard rusher who will miss the first four games of the season because of a suspension for violating the NFL's policy on performance-enhancing drugs. 

Kamara seems like the obvious person to pick up the bulk of those carries. Even after Peterson was traded, Kamara averaged only 8.75 carries per game. A bump to 14 or 15 carries per game seems like the obvious play with Ingram out of action. 

Except that Saints coach Sean Payton has already thrown a little bit of water on that fire, saying two weeks ago that it would be a "mistake" to automatically give Kamara 15 more touches per game. 

Kamara's role might change a little in the first four games, but New Orleans wants to keep wear and tear off of its prized possession early next season. 

"He's excelled with the ratio he's had, whether it's the carries, the combination with the catches," running backs coach Joel Thomas said. "It's almost a number that you want to get to where he's still getting the number of touches he's had in the past, maybe with a few more carries." 

For his part, Kamara resisted the temptation to lobby for more carries when he was asked about the possibility on Monday. 

"From the beginning, I've said whatever I have to do," Kamara said. "I trust Sean, and I trust our coaches, so however it unfolds, we'll just handle it."

Despite all of his travels, Kamara has been working hard this offseason. 

Always entertaining, Kamara has been working on something specific, although he coyly declined to outline his goals in detail on Monday with a smile. 

From a big-picture standpoint, he's focused on being even better than he was when he took the NFL by storm a year ago. 

"I keep moving forward," Kamara said. "I'm always looking for the next, what can I accomplish next?"
