And you can be involved with the throwing of the disc or the catching of the disc.
So put simply, there are four quadrants for the on-field roles: thrower and cutter (on offence), and their defensive counterparts, marker and guarder.
It can be worthwhile to evaluate which of these are your strengths, and which you have to work on.
Obviously the thrower role is critical for every player - a team with mostly poor throwers is not a strong team.
I think that the skills of a guarder are under-evaluated. Many folks I know have a very simple approach to guarding: "stay open-side, chase my cutter, get a block if can". There isn't much adapting to circumstance, and while you won't go too wrong, that isn't enough at the elite level. The corresponding skills for throwing, cutting and marking are far longer lists in the conscious and subconscious minds of many players.
There are many small goals and skills for a guarder:
- Unnerve the cutter with my positioning
- Talk to teammates
- Steer the cutter back to the other defenders in the stack
- Choose when to look over at the thrower and their stance
- Bait the huck
- Take a charge
- Look to switch with a mismatched teammate
