The 23-year-old Ehlers comes into his fifth NHL season one point shy of 200 for his career and needs 10 more goals to reach 100.
He scored 21 goals in 62 games last season, marking the third time he's hit the 20-goal mark in his career.
"This guy is going to score, I don't know, 20 to 40 goals over the course of his year really consistently for us," said Maurice. "Where his minutes come up is durability and effectiveness away from the puck. In order to do that, you have to put the time in. I think he did."
Since he played his first game in 2015, Ehlers has learned what he needs to do in camp to be ready for the regular season.
"I want to play as much as I can," Ehlers said. "I think for me is the best way to get ready for the regular season is playing games. For some guys it's different. If I put a number on it - four, maybe five - I'm good with that."
Before the games come though (the first preseason game comes on Monday in Edmonton against the Oilers), Ehlers and the other 47 players in camp have to get through practices like Saturday's: a full 90 minutes of rushes and battle drills.
And they didn't take it easy on each other.
"There are guys that are trying to make this team. There are guys that are trying to keep their place on this team. It would surprise me if it wasn't like that," Ehlers said. "Everyone wants to play well, everyone wants to work hard, and show the bosses that they can play NHL hockey."
The speedy winger will recover tonight, then do it all over again on Sunday.
During the grind that is camp, Ehlers says he stays focused on the little things.
"You want to get back into skating more and playing games - getting all the small details right before the season starts," Ehlers said. "I've had really good preparation to do my best at camp and put myself in a good position. I feel really good right now and I just need to continue working."
