A Victorian London-thick gas-lamps-on-darkened-cobblestone-sidesteets fog was settling over top of McMahon Stadium for Sunday’s 10:30 a.m. walk-through.

Only an hour earlier, though, the fog had finally lifted over Bo Levi Mitchell’s fluctuating status had cleared with the official release of the Calgary Stampeders’ Depth Chart for Labour Day Monday.

In Bo-Land, at any rate, the sky had turned a bright, cloudless blue.

“The hardest part,’’ Bo Levi Mitchell is saying of his extended wait to return, “was feeling ready and then coming out here and my arm not reacting the way that I wanted it to.

“It would feel great one day before, then the next day I’d come out to throw and my pec would grab and I’d just be kinda super-frustrated by that. It would cause hesitation at times to go out and throw.

“At one point, I just said F-it and went as hard as I could on rehab. And they were like: ‘All right, take it easy.’ But I kinda got to the point of being tired of guys telling me to take it easy.

“So I just started hitting it harder. As soon as I started doing that, honestly, I think things started to respond.”

After being put through more stops and starts than a nosediving hockey team being put through a bag-skate, Mitchell has received an all-clear to re-entry the fray.

He last played, remember, since near the close of the second fixture of the season, June 29 against B.C.

“Honestly,’’ enthuses Stamps’ rookie wideout Michael Klukas, a local boy who spent a years watching the two-time MOP perform his feats of derring do, “having Bo come back is almost a feeling within our team and around the league, too, I’m sure, that a storm’s on the way. We know what he brings to the table. He’s the best player in the CFL.

“We have a great relationship. He’s taken on the role of big brother to me since I got on the team.

“That being side, I think it’s fair to say Nick isn’t just a future star in this league. He came in and played like a star.

“I love being in the huddle with both of them.

“But with Bo, there’s just something special. An aura, I guess you could call it. When you think of the dominance of the Calgary Stampeders, you automatically think of 19.”

In Mitchell’s stead, Nick Arbuckle has, as mentioned, performed admirably, far above his pro experience level.

“With me, personally, I don’t pay too much attention to who’s back there,’’ says slotback Richard Sindani. “I think Nick’s a great quarterback in his own right.

“I’m confident with both of them.

“Nick’s done a great job of keeping us right in thick of things. When Nick first started, you didn’t know what expect. But when he’s playing the way he did, organizing the offence the way he did, orchestrating things, manufacturing plays the way he did, I didn’t really notice much of a drop-off.

“It was just me doing my job.”

Mitchell, too, heaps nothing but praise for his 25-year-old understudy.

“In my mind, the thing that made being on the sideline easier is watching the guy play. I thought Nick played outstanding for a young guy, sharp on his reads, made plays that maybe he wasn’t expected to make.

“He didn’t try to be me. He just went out and played like himself. That was huge.”

Now the Stamps, aiming to push to vie for another West Division crown, are banking on Bo Levi being his peerless self.

“It feels … right,’’ is how Reggie Begelton describes the sensation of Mitchell’s presence. “Him being in the huddle, everything’s crisp. He sees things, strictly through experience, that a rookie quarterback doesn’t.

“It’s almost like having your favourite chef back at your favourite restaurant. The cooking, you know, is gonna taste right.

“The meal’s going to be just the way you like it.”

Coach Dave Dickenson is among the throng eager to see what’s on the bill of fare.

“Bo’s done everything well this week,’’ estimates the boss. “Kinda weird cause you’re in Game 10 but you’re probably going to get a few potential lack-of-playing-time type of decisions. Bo not being AS shape with his eyes. He hasn’t been hit in a long time. Those are questions that need to be answered.

“I’m looking forward to him playing and leading us to a win. But I also know he hasn’t played now for a couple of months.”

So after seven weeks absent from the tour, Jagger’s back in his sequinned jump-suit fronting the Stones again. And, given the occasion, the opponent, the day, the circumstances, itching to launch into Jumping Jack Flash right off the hop.

Bo, at last, is a go.

“I don’t want to take anything away from the other guy,’’ says Mitchell, “but I bring confidence to this game game and I believe guys feed off it.

“I think they understand how I feel about myself, my play and what I can do to win games. Make the big throws, take the big hits.

“I’ve always felt that way. Somebody who hasn’t been there before, you don’t how how they’re going to respond.

“They know how I perform on Labour Day.

“I know how I perform on Labour Day. And through the second half of seasons.

“Our records have been pretty good in both, I’d say.

“When it comes down to making a Hail Mary throw or fitting something into a plate-sized window, they know I’m that guy; that I’m willing to take those chances to make the plays necessary to win a game.

“So let’s get at it.”
