So let me double treble quadruple check! As SOON as I make the mark the team can go, and I can make this as fast as I like? (I like a quick game!).
I tend to make it pretty sharpish if the need arises, and have only stopped someone going quick again once as I had to bin the cynical cheat! Just checking I can do that.
Game management comes in here. If you've awarded a PK and have had to march the offenders back 10, "something" is going on - there's a risk you may be losing the trust or respect of the players. Knowing (as we do but they don't) that there is this urban myth out there, you are at liberty to dash as fast as you can the new mark and dig in your heel to make the mark - but in doing so, what does that do to the "something" that is already bubbling under the surface? You risk having the game get away from you, on account of your wish to demonstrate your superior technical knowledge.
Many of us take the view that if we stride purposefully toward the new mark, signalling and verbalising all the while what's going on, then that gives the offending team the opportunity to reorganise should they choose to take it. Most of us can then say that if you guys can't react while an old fart like me waddles to the mark, shame on you! Sadly, young bucks like jonesp92 will have to think of smart remarks that suit them. However, the point is there; if they've sat back on their haunches despite your clear indications and lack of undue haste, they have no-one to blame but themselves.
