Having a strategy is very important. Also the type of league and league size helps determine strategy as well. If you are drafting for roto and it's a deep league, I recommend only drafting power/speed combo guys early. Don't get sucked into taking Ryan Howard,Josh Hamilton or Miguel Cabrera types early. They put up great numbers, don't get me wrong, but there are only so many SB guys out there. Of the SB guys, almost all are OF's or 2B/SS. With Arod's injury, only David Wright and Chone Figgins are capable of 20+ SB's from the 1B/3B slots. Know how many SB it takes to be competitive in your league. Understand that drafting Jimmy Rollins and Brandon Phillips early on nets you 60+SB and will still get you decent HR totals. You can grab HR later and for cheap. There are plenty of 1B/3B power options around picks 150-250. You will be fine with a 1B like LaRoche,Konerko,Giambi and a 3B like Beltre,Encarnacion or Gordon. The 2B/SS options that late won't have the power and only a few remaining still have speed, but you are giving up power.(think Theriot or Kaz Matsui)
OF's are also a good source of SB as well. Be careful when drafting OF's early. Grab Beltran,Soriano,Rios, Kemp,McClouth,Hart,Abreu types before you consider Quentin,Manny,Magglio or Vlad. I also try to steer clear of OF's who are just speed and not power. Don't waste a pick on Ichiro,Crawford or Ellsbury. I like to grab a 20/20 guy over a 10/40. If you are fortunate to grab a Sizemore or Hanley early, who will get 30HR and 30 SB, then I think it's OK grabbing the 10/40 guy. There are also values late for OF SB guys like Taveres,Bourne,Gomez,Owens. In fact, alot of these guys will even steal more bases(30-60). They are good fallbacks in case you falter in getting SB. But once one of these guys start going off the board, they all go, because owners are trying to sure up SB since they neglected them early. If you play in a deep league, you may have up to 30 picks between selections. You don't want to be shut out. So grab your SB early and often, but make sure you are grabbing them with power if you can too.
