David, Patrick is right on the money with essential footwork. A quick checklist for you below: 1) ensure both props are at the height set by the hooker (he's the boss) 2) ensure both props' inside shoulders are "proud" of the hooker and square and aligned with hips and "spines" in-line, same applies to 2nd rows 3) Make sure the tight 5 engage together as a unit on the E of "engage" and hold the hit (maybe one of the props is not holding the hit) - needs tight hips and good binding. 2nd rows should struggle slightly to get heads in 4) try swapping the loose head and tight head how they understand each other's role and identify where the wheel is happening 5) traditionally the strongest of the 2nd row normally goes behind the tight head but you could swamp them to ensure they understand how the tight 5 unit is supposed to operate. Poor footwork and swinging backside (where hips are not close together in front row) are normally the fault of unintentional wheels. Let us know how you get on. Good Luck ... Dave
