Every poster has their own criteria for selecting. There's nothing specified about that on this thread (IE: don't take his salary/background/experience/position into account). With that in mind, I think every opinion is valid.
For my pick (Dice), I'm valuing more inside defense, because I personally think that's a weakness we have when TD sits down, and I think Dice has done a great job filling that need for this bench. For me, having that is more important than Hill's offense and defense (which might be the best in the team, but it's been inconsistent, IMO).
I'm sure other people value other things, and takes them to a different selection and that's fine.
