Calvin Armstrong is a tough marker.
While the Edmonton Eskimos coaches were very pleased with Armstrong's debut as a starting left guard in last week's win against Calgary, the rookie is pointing out his mistakes.
"I grade myself pretty hard and I wasn't the happiest," said Armstrong, who replaced the injured Dan Comiskey.
"I don't think it was the best game I played in my life. I got a lot of room to improve."
In specific, Armstrong feels there were some problems involving the run game.
"Just little mistakes I made in the running game. I think I cost us a couple of first downs in the run game," he remarked.
"It shatters our confidence and coaches don't want to run the ball anymore.
"It screws everybody when stuff like that happens."
Edmonton head coach Danny Maciocia had a much better review on the import's first regular-season start in the CFL as a guard.
"He played really well," said Maciocia. "We've got a lineman of the week (award) and he was the recipient of that."
SHAPING UP: AFTER PENALTY PROBLEMS LAST YEAR, THE ESKIMOS HAVE CLEANED UP THEIR ACT THROUGH THE FIRST TWO WEEKS OF THE REGULAR SEASON.
On offence, Edmonton has the fewest penalties in the league with just 13.
In comparison, Toronto - this week's opponent for the Green and Gold - has 24 infractions.
"We are much more disciplined. We have drilled it hard enough that I think the message is starting to get across," said Maciocia.
"We are making sure everybody is taking accountability out there.
"And when things happen that shouldn't happen, basically they are going to get called out in a team meeting and they are going to have to address it.
"And it could be a humbling experience when you stand up before your peers and try to justify what took place in a game."
