Assuming the 40-Second play clock goes favorably in Michigan, Indiana, and Colorado I would think the NFHS would be faced with a dilemma.
25-Second Play Clocks simply supplement the existing Rule.
40-Second Play Clocks would require changes to the Rules.
Since 25-Second play clocks are not even required equipment, I would not expect to see any rules changes to support the use of 40-Second play clocks.
Additionally, any attempts to change, modify, or replace the 25-Second rule (3-6-2d) to include a 40-second method, BEFORE requiring visible play clocks will not even last half as long as NEW COKE.
Why?
I'[ll take one state for example. Oregon
In Oregon of the 236 High Schools that participate in NFHS High School football exactly ZERO will have visible game clocks on their fields in 2016.
Ready-Ref offers a 2 clock, 3, Controller, 2 rolling cart system for $8,750.00
Assuming you could make a mass purchase and go the price down to $6000.00 per site that is:
$1,416,000.00 with a price break or $2,065,000.00 without a break.
I don't see the town barber, or even the local mortuary stepping up to pay that bill.
While we have one possible equipment manufacturer in Oregon that would come to mind, currently there business stays are pretty busy making shoes, sox, calf bands, gun bands, head bands, sweat bands, off the wall Jerseys with matching pants.
Besides even if they did step up, it is likely the word NIKE would be so big,
the Back Judge would have trouple seeing the digits...
Not likely to happen boys, you would have better odds supporting the triumphant return of NEW COKE!
