3 man team? practise for uttoxeter?
running and gunning would be a good one to practice
find a barrel or a box or something and stick it in the middle of the lane to one of the outside corners. now get your guys to walk quick/run to the outside corner while gunning. then thyll learn how to a) run and gun so they can move bunkers and gun a position if needed b) how to lane a zone.
then when youve got that going get someone to do the oppisite back to them, see how they cope under the pressure of being shot back at.
another drill you can do is set up half a field. have a snake down the tape(zipper style ie sausage brick sausage brick etc), two corners, a center, and a mid brick (all in one half of a field). 3 a side,1st one to touch a mid bunker ( so one in the snake or one of the mid ones) wins. this will teach you how as a team you can put a player into a killer bunker and how to lock the field down to stop it happening to you.
if anyone disagrees with that lot then feel free to correct me or say something yourself
