The Calgary Stampeders are not the B.C. Lions when it comes to offensive power, but they will still present a good challenge for the Riders defense.

Quarterback Kevin Glenn has been around the block a few times, and has some good weapons at his disposal, especially receiver Nik Lewis and running back Jon Cornish.

Lewis is a challenge on his own, he's not the tallest receiver but at 240 pounds, he's certainly of the biggest in all of football, let alone the CFL.

"I wouldn't necessarily say stop, but you try to contain him," said defensive back Eddie Russ.

Lewis' resume is pretty sparking at this point, and he's proven to be a very difficult man to tackle because of his size. So defenders will admit, you have to play him differently.

"You can't cover him like a regular fast guy," said Russ. "He's athletic, he's got ballerina balance, and he can jump over you."

One thing Russ says they will have to do to try and slow down Lewis, is to hit him hard, early and often.

"You don't want to get him running downhill at you," said Russ. "Because that's a big bus coming down at you."

That game plan worked to perfection last time the Riders faced the Stamps on Cornish, when early in the game linebacker Tyron Brackenridge laid a good lick on Cornish. That will be the game plan again on Saturday afternoon.

"We thought he had a concussion, he dropped a few balls after that," said Russ. "That's the tone we want to establish early in the game. We want to hit him hard, and let him know we're going to hit all day."
