How about icing the foul-shooter in basketball? Should that be banned, also?
Here's the way I see it. Timeouts are a resource. A valuable resource and a finite resource. If a team saves that resource for the end of the game, they likely have had to make a conscious decision to do so somewhere along the line, possibly to their detriment. So, if they've hoarded that resource, they should be allowed to use it as they see fit.
Should a losing team on defense be allowed to call timeout on three consecutive plays? Surely, that disrupts the natural flow of the game more than a single timeout to ice the kicker.
Besides, that ship sailed along time ago. Around the time the TV folks decided they could have a TV timeout following an extra point, have a kickoff, and then have another TV timeout. Have that sequence around the end of a quarter and you can have two or three plays from scrimmage in real-world time of seven or eight minutes. That jerks my chain a lot more than icing the kicker.
One of these the Pats will stop icing the kicker. NFL coaches, being members of the herd, will follow soon after.
Problem solved.
