"The plan is to keep them. Next year, yes. And my plan is to always keep them," Monfort told The Denver Post on Wednesday. "Is that the smartest thing in the world to do? I don't know. But for our fans I think it's the best thing to do."
Gonzalez batted .302 with 26 home runs and 70 RBIs this season despite playing in just 110 games. The left fielder missed the final two months of the season with a sprained right middle finger and opted against surgery after playing in instructional-league games last week in Arizona.
Tulowitzki, despite having missed just under a month because of a rib injury, again put up elite numbers for a shortstop, batting .315 and adding 81 RBIs to go along with 25 home runs.
"I love those two guys," Monfort told the Post. "And if they ever get on a tear ... in Tampa Bay, every once in a while, Evan Longoria just carries them, and we have two guys who can carry a team."
The Rockies finished last in the National League West and haven't reached the playoffs since 2009.
"I would say if Oakland, Tampa Bay and Pittsburgh can win, there's no reason we can't," Monfort said.
