Let's not get overly excited about walks, to me they are only valuable if they eventually lead to a higher batting average or stolen bases. Or for those of you in leagues where runs count. You're not going to get stolen bases from Ike Davis, so he's still riding my bench until he can show an ability to consistently keep that batting average up. Walks can often just be a sign of being in a really poor lineup - for example, if Beltre starts walking more in Nelson Cruz's absence.
In what leagues do RUNS not count?? Seems a pretty standard fantasy category. And the walks also help with OPS, which is a popular fantasy category.
