It will take a club record offer to land free agent righthander Yu Darvish, and the Twins are very aware of that.

But as they continue to look at Darvish as a top priority this offseason, the biggest concern is not just the money, it's the length of the contract that will be required to land him.

To be clear, there has been no indications that Darvish has received an contract offer from the Twins or any team. Darvish himself shot down a Twitter report on Thursday that claimed he signed with the Cubs, calling it, "fake news." The Cubs, Astros and Rangers have expressed interest in Darvish, with the Dodgers and Yankees possibly in the mix as well. The Twins have not visited Darvish, like the Cubs and Astros have, but hope to get a meeting with him.

The Twins have never signed a pitcher for longer than a four year contract. But the top pitchers in the game -- Clayton Kershaw, Stephen Strasburg, Max Scherzer, Zack Greinke, Felix Hernandez, Justin Verlander and others -- have inked six- or seven- year deals.
