The Rockies and Nolan Arenado are working toward a multi-year extension that would keep the All-Star third baseman in Colorado well into the next decade, potentially allowing him to finish his career in the only Major League uniform he's ever worn.

Although no deal has been completed, Rockies owner, chairman and CEO Dick Monfort appeared optimistic that the two sides were nearing the finish line.

"I think we've gotten it to the point where we're to the finals," Monfort told last weekend. "We're to the crescendo."

With Manny Machado and Bryce Harper still searching for free-agent deals, what might an Arenado extension mean for the two superstars -- and for the rest of the game? Here's a look at some potential ripple effects should Arenado and the Rockies strike a deal.

Would an Arenado extension impact the markets for Machado and Harper?
Arenado -- who is eligible to become a free agent next winter -- and the Rockies agreed to a one-year, $26 million deal last week, avoiding an arbitration hearing. An extension would likely pay Arenado a higher average annual value (AAV), potentially setting a new record for a position player.

Machado and Harper were expected to set that standard this winter, but the 26-year-old All-Stars have struggled to find deals they consider acceptable. According to a source, it's entirely possible that neither player signs before March, so it will be interesting to see whether the Rockies and Arenado announce an extension before either player signs a new contract.
