Just a timeout mechanic I picked up from a college guy 5-7 years ago. If this helps, great.
All too often I will go to a HS game and after the timeout (tweet-tweet) 45-second warning it takes teams another 30-45 seconds for the RFP.
Why are we waiting for them to linger, walk back on the field?
When BJ gives his 45-second notification, LJ & HL, instead of "let's go guys" - and getting ignored by the coach; each should tell the team huddled on their sideline, "this play will be chopped in in 15 seconds" - and then do a verbal countdown 15, 14, 13....all this while R is looking to each with a look of "here we go".
No motivating, begging needed.
From my experience, the results will impress you...
