Ask fantasy baseball owners and they'll tell you Kemp is one of the most polarizing players in baseball.
Kemp's 2009 numbers: .297, 26 HR, 101 RBI, 34 SB (8 CS), 97 R, .842 OPS
Kemp's 2010 numbers: .249, 28 HR, 89 RBI, 19 SB (15 CS), 82 R, .760 OPS
The stolen-base success is a big worry, along with the batting average, of course. He was successful on 80 percent of his steals in 2009, and then only 55 percent last season. If he is in the 80-percent range, then he steals 30 more bases and creates runs. If he stays around 60 percent, then he might steal 20 per season.
If he bats .249, that's a lot of runners left on base, but if he bats over .290, then he knocks in 100-plus. As the main run-producer for this team, that could be a five-to-10 win swing.
