a) Probably depends on the team in question. I can see a stacked team dropping Benitez in order to pick up someone they simply couldn't pass up, especially if benches are small. There should still be a place for Benitez in a 12-team league, though, especially if it's roto.
b) That's a bit odd; all the bad press Benitez is getting is probably to blame.
c) Tough call. Benitez and Looper probably aren't that far apart at the moment.
Congrats on picking him up.
