The lack of such an offer now doesn't mean he'll never get one, either. Remember the 2011-2012 off-season? Do you recall all of the questions surrounding Prince Fielder, about how Boras might have finally overplayed his hand, and that Fielder would need to take a short-term deal with a lofty average annual value, because this time things would be different, no one would crack, no one would give in? On Jan. 26, 2012, that all went out the window, with Fielder signing a nine-year, $214 million contract with the Tigers.
Doubting Boras is generally futile.
This is especially true when the talent in question is as immense as Choo. He wasn't, and arguably still is not, a household name, but his numbers sure are. Choo ranks 12th in the majors in OPS+ since 2008, minimum 3,000 plate appearances, directly behind David Ortiz, while ahead of players you hear far more about far more often in Evan Longoria, David Wright, Carlos Beltran, Josh Hamilton, Hanley Ramirez, and, wait for it: $240 million man Robinson Cano. The fact he's coming off of a great season in which he batted .285/.423/.462 and earned over four wins above replacement in spite of playing poor defense out of position in center field will help as well. If a club is signing Choo to be a corner outfielder, he's likely to be more valuable than he was in 2013, simply because he's a more natural fit there, and his bat can absolutely handle even the rigors of right.
He'll be 31 in 2014, but that's actually a year younger than Werth was in his first year with the Nationals. With one exception, Choo has been on the field for at least 144 games in every season since becoming a full-time player. On-base percentages like his, especially coupled with power and the ability to make consistent, quality contact, are such a rarity on the open market that someone cannot help but pay him what he asks for, or something approximating it, because it's the only way to acquire that level of talent short of finding it yourself in the draft or internationally.
