Don't overspend to target Taveras

The trade of John Lackey for Allen Craig and Joe Kelly is, on the surface, really good news for St. Louis Cardinals rookie outfielder Oscar Taveras, because it opens up right field for him on a full-time basis. But what if Taveras just isn't ready to be any good at this level yet? I mean, he's 22 years old, and while it's way too early to judge him on a long-term basis after 100 or so big league at-bats, what are fantasy owners really expecting here? Taveras has been compared to former fantasy star Vladimir Guerrero because of his high-leverage swing and propensity to swing at anything and everything, a noted bad-ball hitter. And he has generally succeeded in the minors.

But Guerrero never struggled like Taveras has this season.
