In a game last night, we were playing Zone D (3-3-1) and one of our teammates called a pick. He was playing mid-mid (I think) and felt
that he another offensive player (say mid-popper) got between him and a side-popper that he believed he was covering at the time. The response from the other team was, "you're playing zone, you can't call a pick".
I wanted to get some opinions of pick or block calls when playing Zone D.
In Cup: I've never thought about calling a pick or block when I'm in the cup and the disc is swinging. Many times, I might have to run around a popper, but that's just because we're all moving around (sometimes in apparent chaos). The disc and associated player is typically more than 10' away, so I obviously shouldn't call a pick... and I'm not sure block is appropriate either (disc in air, but popper isn't playing me... disc in hand, and well, the popper's position is typically avoidable as long as I stay aware).
Mids (mid-mid or hammer-stoppers) and deep: I suppose picks would be a very valid call here... as long as you're within 10' of whomever you truly believe you're defending within your area, and someone else causes you to lose your position on that person. Blocks... again, rather unlikely, but perhaps in the right situation.
Those are my thoughts on it... I'd like to hear any of yours.
