The debate rages on whether a poke-prod-and-punish approach to handling Ovechkin either A) awakens him; he feeds off it, making him even more dangerous or B) it ticks him off; throws him off plot.
One thing is for certain, when in top gear, the man's practically unstoppable.
"Once he's coming down on you, with speed,'' says Engelland, "if you don't have a good gap he can make you look pretty silly. Quick.
"On the flip side, if you're playing him tight and don't give him that room to get going, that's your best chance. Limit the offensive zone time and play in their end is our best weapon."
With the Caps, Flames' coach Glen Gulutzan isn't shy in admitting he considers this a litmus test, a polygraph, for his young group.
In the morning, for a bit of inspiration, he showed the Flames a video of the New England Patriots.,
"We watched a little Bill Belichek talking about emotion and energy and a little bit of how they get ready."
Does this mean the Flames might deflate the pucks?
"We might,'' admitted Gulutzan, smiling. "We just might make 'em a little softer, with Ovie shooting."
Clearly, though, in terms of assessing progress level, the coach relishes putting a three-game win streak on the line against a team as formidable as the Caps.
"We talked about a measuring stick,'' said Gulutzan. "This is where your leadership needs to step up.
"It's a real man's game tonight against a real good hockey club.
"It's a really good game for us at this point. We talked about digging in and getting everything stabilized here and now we've got a team that we can grow from.
"They're a highly-evolved team that won the President's Trophy last year and did it with realize ease."
One of the deepest of all NHL outfits, chock-a-block with skilled, impact players - Ovechkin, Nicklas Backstrom, Marcus Johansson, Evgeny Kuznetsov, T.J. Oshie, Matt Niskanen - the Capitals test an opponent's nerve and its discipline.
Discipline, of course is an area that Gulutzan is demanding his team clean up.
"We talked about that. We talked about emotion and having it. We're going to be tested as a team, the discipline within that emotion in the game, playing within those boundaries.
"This is a growth game for us. We're going to get more out of this game, if we play the way we want to, than Washington will.
"That's why we're talking about taking a bite out of them today. It's a growth game for our team."
