This month the league will be looking at whether it should change the rules governing replay challenges again. Personally, I loved Ambrosie's decision to reduce the number of replay calls to one per team per game, along with an automatic review of all scoring plays, as the extra reviews were slowing down the flow of the game too much. Having one per game also made the use of the flag to demand a replay review a strategic decision, rather than a search for a penalty call because one had more flags to throw if the current one didn't work out.
Furthermore, my sense was that last year most fans welcomed Ambrosie's change of this rule.

It’s clear the league’s aggressive approach to replay struck a tipping point early last summer when a mid-season intervention became necessary.

With teams able to use as many as three challenges per game, coaches began using them not just to overturn incorrect calls, but also to search for possible penalties that might negate plays that went against them.

If the opposition made a big offensive play, why not toss a challenge flag and ask the command centre to look for illegal contact on a receiver? Give coaches a low-risk, high-reward tactic and they’re going to use it.

The problem is the games slowed to a crawl.

Among the viewers who found the game unwatchable was new commissioner Randy Ambrosie, who rallied his troops to make a mid-season rule change that restricted coaches to just one challenge per game.

“We went too far, too fast,” said Ottawa general manager Marcel Desjardins. “There’s a fine line.”

Under Ambrosie’s direction, the importance of getting a call right has to be balanced against something called “game flow,” a topic that soared to the top of his priorities last summer and has remained there ever since.

“It’s clear that replay really impacts the flow of the game from a player, coach or fan perspective,” said CFL senior director of officiating Darren Hackwood. “It’s all the same and they don’t want these negative stoppages. It impacts the officials too, everybody. It’s a balance between using replay for its intended purpose and limiting it so we’re not impacting the game flow.”

One option the league’s rules committee is expected to discuss in March is allowing the command centre to correct some officiating mistakes without there needing to be a challenge and subsequent delay.

For example, should the command centre spot an obvious situation where a receiver is ruled in-bounds when replay clearly shows he is out, should it be allowed to overrule the call on the field without a team needing to burn its only challenge?
