Agree, and I hate to say it, but maybe other clubs just view him as too -- I want to say unreliable, but inconsistent to give up major assets (in a way, that may be why Giolito is still unsigned).
And I know it's easy for posters to look at crappy current stats for all the big names we didn't sign or trade for, but I personally don't think all those numbers automatically transfer to a different home park, line-up, fan base, media market etc.
Bogaerts may be an example, since he thrived more in Fenway than Petco: ..312/870 to .272/.747. Of course, age is also one of the many other factors -- but we just don't know which ones really count... Machado .297/.890 at Camden Yards, .274/.832 at Petco.
Maybe perfect weather every day of the year makes it just too hard to focus on any job in San Diego?
