Nothing about this is simple. So a player who is cramping needs a 5 to 10 minute medical exam in the tunnel? Who tracks the time requirements? A literal 10 minutes or 10 game clock minutes? What happens if a team violates these time minimums? Are those penalities the ref calls on the field? Here's what is simple: football is a game where coaches are going to mitigate against any advantage the other team has. Team A goes fast to gain an advantage by not allowing Team B to substitute or or get properly aligned, Team B will slow them down, however they can. That's simple.
People like you kill me. You overcomplicate everything in an attempt to find an excuse that your opinion is correct.
Yes, if a player is cramping so bad that the game needs to be stopped to remove him, then that player would be taken to the tunnel/medical review area where actual sports physicians could exam him, and in seeing that he has actual cramps, not mystery ones that disappear once you cross the big freaking white line on the side of the field, they will administer fluids and massage, etc. This physicians examination would the time determining factor. Checking pupillary responses, checking hearing, etc etc etc, now if a player is brought to this area with obvious signs of an injury, let's say a broken finger skewed at an inappropriate angle then I'm sure they would focus on this. Let's not pretend that these physicians don't already exist, nor that they don't already have some form of routine examinations they perform. Concussion protocol anyone? It's not a penalty that I'm saying needs to be done, just that any injury that requires a stoppage in play needs more than a freaking water bottle ran out to them, a shoulder to lightly lean on so you can then walk over the magical sideline healing zone, get some coaching and then return to field for the very next play.
The idea is simple. Make an examination standard that goes through a full body checkout, imagine the concept of a vehicle 20 point inspection(tire pressure, oil level, washer fluid, etc). This exam can be focused depending on what the player informs the staff, "It hurts here, see, my nose is broken". Barring a specific injury, this examination would take actual time, 5 to 15 minutes, during which the player is unavailable. All reports of cramping would require a stretching and massage regimen, and an increase of sports fluids before return to the field. If said player returns to the physicians again with cramps during the game again, he would need taken inside the locker room for blood/urine testing to see his potassium/calcium/magnesium and etc levels and be administered the necessary treatment. If he was actually injured, then they will find the problem and start treatment. This isn't a penalty system, it's not a time out. It's in the interest of player safety that any player who cannot physically exit the field of play efficiently is one who deserves to be looked at by trained medical staff and cleared to play again. Instead of coaches using this tactic as a free timeout, they would know that that player has to go through medical protocols and would be unable to return until he had passed those, which takes X amount of time. As it stands right now, there is no requirement that a possibly injured player is required to receive any form of medical examination/treatment, only that he can if he indicates that he is actually injured, with the exception of concussions. Concussion protocol examinations can be determined by sideline medical personnel, coaches and the booth overseer. I'm simply suggesting the addition of an injury protocol that is triggered by the need to stop the play clock to remove them from the field of play. A protocol that would take more then 2 seconds to ask, "You good".
And your idea that,"Team A does this and team B does this, it's simple." It doesn't hold water. Pro and College Football has enacted many rules over the decades in the interest of fair play. Horse collaring, jamming wide receivers, after the flag hits, spearing, unnecessary roughness, holding, tear away jerseys, stickum, etc. Some of these are for competition purposes, others for player safety, and some, just because.
As it is, I'm done with this subject and you. Thanks for joining the ignore list here, but you have fun.
