Mainly watched wings and deep guys. Here's a few comments. As always meant to help not to show anyone up, so read with a thick skin mates!
1:10
LJ should be backing up and working reverse mechanics, ie swapping "hats" with the FJ. FJ follows the play and gets the progress, LJ stays in front of the play.
1:33
Nice job by SJ. Gets to and stays at GL, retreats backwards for own protection but still on the GL to rule on the play.
1:40
LJ stay at LOS till pass made, your call as to whether it crosses NZ on a 6 man (unless your mechs are different).
2:43
SJ resist the temptation to look along the GL when you signal the TD. Keep your eyes on the players!! Especially the scorer who may be hit late, or may excessively celebrate etc.
3:28
FJ can't afford to get beat like this. Not moving backwards fast enough. On a medium pass like this, you have to stay deeper than the play, let the wing official get the progress.
3:52
Both HL and LJ too eager to move. Remember you are a 6 man crew, you have deep help, but you are both working as if you are a 4 man crew. Stay at the LOS. HL's key (the inside receiver) has at most gone 5yds downfield so is there any need to move at all to cover him? Whilst most Mech manuals say that on a 6 man the HL is allowed to move up to 5 yds downfield, it does not say that he MUST. LJ moves off well downfield when he ought to stay at the LOS. The QB does not cross the LOS before the pass but he might have and on a 6 man that is the LJ's call. If the QB had tucked the ball away and run hard for the sideline, he probably would've made perhaps 7 yards and gone OOB right where the LJ was, thus endangering him.
4:01
FJ beaten again. Walking slowly backwards. Does not appear to be watching his key, but watching the QB? Hence he does not pick up on how far and fast downfield his key and defender have moved. Should have been as deep as the SJ was at the conclusion of this play.
4:07
Wings should snap straight to the GL faster than they are doing. Be there before the ball carrier. You can always work back to the spot if he is stopped short.
4:17
LJ drifted downfield. If he had stayed at LOS, then he could have more easily gone into reverse mechanics. On this play the progress spot is the FJ's.
4:38
SJ. At 4:43 he is still out of camera shot thus proving he is nice and deep. At 4:44 he has realised the GL is threatened so turned to sprint to it and manages to just about beats the player to the GL. Nice job.
5:02
LJ again has "happy feet" and moved off as if he is in a 4 man. At 5:09 HL a little too eager to be moving downfield. At 5:13 the SJ is in camera shot and really shouldn't be. Also his bodyshape is wrong, he should be backpedalling, not be facing the field. Perhaps he's assumed the runner is going to be stopped. He's wrong, the runner is smart enough to follow his blocks and makes more yards, he's only stopped virtually at the SJ's feet. This play is the HL's progress spot all the way (to the 2yd line), SJ should try to stay well downfield of it.
5:37
SJ Again, be looking at players, not along the GL at your deep partner. It is OK to pivot your body to watch them. Many officials seem to thnk you have to be 90 degress to the sideline either looking in or out. I say - imagine you just finished a dribble in basketball, you don't want to get called for travelling, but you are still allowed to pivot to face any direction you want.
5:40
Is this the LJ working ahead of the runner? Not where he should be. Always take spots from behind.
5:52
FJ look at players, not along GL.
6:00
SJ Nice job getting to and stopping at GL. But then you start coming back toward the play as soon as one defender has the receiver. You are assuming he's stopped, he might break free and it is not gonna be your progress spot anyway, so stay put! Only collapse in toward the pile once he is definitely down. Let the LJ get the spot which he does correctly facing out to watch players, but maybe gets there just a little too quick for his own safety.
6:13
FJ On this slow developing run you should stay backpedalling all the way and be moving faster. At 6:19 you've realised he's broken a couple of tackles and heading straight for you and now you are too close and endangered. Where you should be is at the 35 and still backpedalling. Luckily for you the D step up and manage to tackle him.
