The two tattoos — one on the inside of his right wrist (his dad, mom, and sister’s birthdates in Roman numerals) and a family inspired design on his right bicep (done by Brian McGrattan’s tattoo artist) — those are new.

The extra 10 to 12 pounds of bulk added to his six-foot-two frame, that’s also different.

The haircut, sure, that’s new, too.

But appearances aside, No. 23 is still No. 23.

No fuss. All business. Straight to the point. The same as the day arrived on scene a year ago for the start of the Calgary Flames 2013-14 campaign.

“Things go by quickly,” said Sean Monahan, promoting the release of EA Sports NHL ’15 on Tuesday and signing autographs at an EB Games store in South Calgary. “You don’t even realize it. It feels like yesterday I was still playing minor hockey. Now, I’m doing this kind of thing. It’s pretty crazy.”

When you think about it, crazy doesn’t begin to describe it.

In over 365 days, the Flames’ sixth overall pick of the 2013 draft went from being the captain of the Ontario Hockey League’s Ottawa 67’s, to the most famous 18-year-old in the city of Calgary, to one of the Flames top scorers and shining stars in a dismal 2013-14 rebuilding campaign, to starring in a video game he used to play as a kid in junior.

This week, instead of packing up his suitcase Thursday and travelling to Penticton, B.C., for the Young Stars Tournament, he’ll be skating informally at WinSport’s facilities along with captain Mark Giordano and others gearing up for the start of main camp next week.

Typical Monahan, though — part of him wishes he was with the prospects.

“It’d still be cool to be there,” said the centreman, referring to the rookie event where it all began for him last year. “But at the end of the day, you want to be with all of the guys and training here, getting ready for the season. I think that’s my main focus right now, to have a solid start and start off on the right page.”

Or, in other words, picking up right where he left off in 2013-14.

After cracking the roster, days before his 19th birthday on Oct. 12, Monahan simply dazzled in his rookie NHL season. He scored 22 goals and had 12 assists in 75 games which put him fifth in team scoring and second in goals behind the now-departed Michael Cammalleri’s 26.

But, still, the Flames finished 35-40-7 and 27th in the NHL.

And that meant there was very little time to waste this summer.

Aside from taking his family on a post-season, post-world championships getaway to the Bahamas for a week — and a trip to Calgary during the Stampede — Monahan was back to work quickly at Toronto’s MasterCard Centre, the Maple Leafs practice facility, with trainer Bryan Marshall.

It paid off with some good muscle mass added which is sure to please new general manager Brad Treliving when Monahan weighs in on Sept. 18, the day players report for fitness testing at main camp.

“Obviously after going through last season, I knew what to expect,” said Monahan who was officially listed at 185 pounds last season but played closer to 200. “I adjusted that this summer and it worked out pretty good, I think. Other than vacation and coming out here, I was at the gym every day.
