coach running down the field to call TO (NCAA)

[TXMike]

The rules do not explicitly permit it but common sense dicates that it be permitted. If the rules permit him to call time out (they do) and you are someplace where he cannot be heard from the 25 (they often cannot), then why not let them come down to call the timeout? They can't come down to berate the crew or give instructions to the team, just to call the TO
