I see one thing that everyone can seem to agree on is that stalling is a very difficult call to make or not make . So it makes sense that most refs would rather just let the kids on the mat settle it thats why they dont call lots of stalling penalties .Which in my experience over 20yrs ,95% of the refs do a good job of doing that. You 5% out there this isnt about you and how smart or different or experienced you are. As someone said earlier the best refs go unnoticed . And the 2 refs I noticed this year were go figure THE WORST REFS I HAVE SEEN THIS YEAR when in doubt swallow your whistle and let the 2 kids decide the result thats all im saying
