After watching some of the competitions from over the weekend I'm much less skeptical of the goalie strategy and I actually think that this could be fairly viable now. Just from watching Southfield and 4854 (I think, my apologies if the number is wrong) a goalie caused serious havoc.

Are there any teams out there that are dedicated goalies or are considering to have a goalie strategy in their back pocket? Particularly any auton goalies that are willing to share their secrets.
