HMP isn't about completing passes...
Its about splitting the defence.
If you can throw the distance of the pitch, you only need a "potential" catcher to force your opponent to keep them covered. If your opponent is silly enough to get out of position (or maybe you force them out of position with a well timed Stun) then you can throw and intentionally miss the pass...
Comfortable in the knowledge that you wont likely fumble and can pick up the ball next turn and walk it in (maybe even add a strutt)
At worst, you can force your opponent back onto the back foot as they desperately scramble to recover from the MASSIVE shift in play!
< Heck, with TTM teams all you need is an opening... HMP the ball into an empty back field, next turn, TTM a runner in to pick it up! >
HMP isn't a skill I'd rush to get on a T1 team, but I'd always have at least one after a while. On T3, you need to be quite a lot trickier...
HMP is just awesome for stunties!
