Arb years are the same as they'd be regardless. What makes this extension great is that we've bought out two free agent years. The back end of his contract, even if he's league average offensively, he'll be making the market value. His defense already makes him way more valuable than any other SS and the offensive potential is definitely there for him to emerge into something even greater.
This might be the extension I'm most excited about. Compare this to what the Rangers gave Elvis Andrus (7 yrs 100+ mil - granted he was closer to FA)...and this could be a major steal in a few years.
