Teams like Detroit, TB, and Milwaukee (ie: bad teams) usually run a lot because they can't score any other way. So it's not always bad to have a guy on a terrible team. But it's a bonus if they're on a good team, like the Marlins, giving an advantage in not only BA and SB, but R as well. I'm grabbing Sanchez in most of my leagues and Pierre in none of them for the reasons you just stated. I know that value wise, Pierre merits a high draft spot, but that's assuming everbody is drafted where they should be. Sanchez is usually a huge steal, same with Roberts. Half of the teams probably bank on getting one of those 2 guys really late, and everybody would be hapy with them, but everybody gets gunshy and feels like it's wrong to draft pure basestealers early unless they're on teams that produce a lot of runs. If Crawford didn't have Huff and Baldelli in his lineup, nobody would mention him in the same breath as Pierre, because "he's on a terrible team; he's one dimensional". I don't get it.
