POSITION SCARCITY - CATCHER OR SHORTSTOP THIS YEAR??

have done very, very well over the last 12+ years of fantasy baseball.  one of my biggest strategies is taking advantage of top-heavy postions.  this year i personally think that shortstop and catcher are the 2 most top heavy postions.  anyone else have a thought on this, and what are your top 3 top heavy postions??

 

2nd base has to be included.  Utley coming off surgery and Kinsler missed time last year.  For me, this is the most difficult position to handicap.  Roberts getting older....who knows if A. Ram can repeat last year's season?  Same with Dustin P. 

 

Some potential there, but a LOT of question marks.
