Marcum is easily over Shields, not terribly close if you ask me.
Jurrjens vs. Ogando is close but I still give the nod to Jurrjens.
Hosmer to Quentin is an upgrade but nothing major, Hosmer looks pretty damn solid, while Quentin is a wildcard. Edge to you but only by a bit.
Overall it's only a mediocre trade, and one that I wouldn't do. You need a more proven arm if you are giving up Marcum, or someone that contributes in more than 2 categories, which is really all Quentin brings to the table.
Goldy is King.
