Hanley. When drafting on the corners, you need to look ahead.
If you sit on stolen bases, you'll end up with someone like Ellsbury, Suzuki, Tavares, Born... who knows? One dimensional players who help in one, maybe two categories but are typically bad news in the HR/RBI department.
According to rookie's MDP report, you can nab Beltran, Soriano, Pedroia, Fielder, Manny, Morneau, Upton, Lee, Quentin or Suzuki with picks 20-30. Thats a nice range for a 12-team league.
I prefer Hanley to complement the players available from picks 20-30. But that's just me - i always like my first picks to perform in as many categories as possible.
