The interview was interrupted by Washington Redskins fans who couldn’t get enough of running back Alfred Morris in training camp last week. And just when our conversation finally got rolling after Morris had posed for pictures and signed every hat jersey and helmet put in front of him a second wave of supporters appeared.

“It’s crazy” Morris said while shaking hands and receiving another round of attaboys. “This time last year even a lot of [team employees] didn’t know my name. I guess I gave the fans a reason to like me.”

More like 1600 of ’em.

The late-round draft pick rocketed to stardom almost as fast as he hits the hole on rushes. In a season Morris went from being a long shot to make the opening 53-man roster out of camp to setting the Redskins’ single-season rushing record with 1613 yards. Don’t be surprised if his second act is even better.

Morris possesses intangibles — smarts vision patience determination — that separate the NFL’s best backs from the average ones. It’s true he benefited from playing alongside quarterback Robert Griffin III in Washington’s option-based offense. Racking up yards is easier when you’re not the defense’s primary concern.

But for anyone who think Morris’s big numbers mostly were a product of Griffin’s ability and offensive coordinator Kyle Shanahan’s play-calling there’s something you need to know: You’re wrong. Morris deserves the majority of credit for his success.

Without Morris’s contribution the Redskins wouldn’t have had the NFL’s most balanced offense last season. Listening to Coach Mike Shanahan praise Morris you get the sense the second-year player won’t be a one-hit wonder.

From the start of last year’s training camp Morris impressed veterans with his hard-charging running style. Before the first preseason game I asked Shanahan whether he thought it was too early to draw comparisons between Morris and former Denver Broncos running back Terrell Davis whom Shanahan also drafted in the sixth round. “It’s not a similar situation — it’s exactly the same” Shanahan said at the time. “When you’ve been in the National Football League a while there are some things you just know the moment you see it. The first time I saw [Morris run in practice] I said ‘Whoa. This guy gives us something we haven’t had.’ It was obvious.”

Statistically Morris had a better rookie season than Davis — an NFL most valuable player and two-time Super Bowl champion whose career was cut short by injuries — in helping the Redskins win their first NFC East title in 13 years. Of course that doesn’t necessarily mean Morris will have a better career than Davis but “there’s no question in my mind that he’s going to be one of the best backs” again this season Shanahan said recently. “He’s going to be a guy [who] just keeps getting better. . . . Now can he surpass what he did last year? I can’t answer that. But I would be surprised if he doesn’t have an excellent year.”

Others around the league agree. En route to finishing second in the NFL in rushing Morris earned a reputation for being a runner who gets the most out of every play. A longtime NFC defensive coach who has studied film of the Redskins doubts backups Roy Helu or Evan Royster would be as successful starting as Morris who “breaks a lot of tackles . . . and is just a way different runner than the other guys.”
