I think the complaining about length of game is overstated. Clocking pitchets and hitters will never work, tried it before and it was a failure.<br /><br />I mean are more people really going to watch games if they average 2:55 instead of 3:05 or whatever the proposed time saving is?
The thing that opened my eyes to the length of game was the fact that games lasting 3.5 hours or more have essentially tripled since 2005 (mentioned in a recent SI article) - they've gone from about 6% of the games to about 18%.
The issue isn't the 2.5-3 hour games, it's the ones that last a lot longer. Sometimes the issue is pitchers; sometimes it's the batters. That's why I'd like both given a time limit (there is an existing unenforced "pitch clock" rule that focuses only on the pitcher). If 80-90% of the games were in the 2:40 - 3:00 range I think most folks would be fine with that.
MLB needs attendance to survive, since much of the revenue is based on gate receipts. Having games that are too long is going to make more people stay home vs. attend the game. Comparatively, it should be looking to something closer to the NHL & NBA length of games, not the NFL.
As far as the ads being the issue, I think the ads are the difference between games being 2.5 - 3 hours vs. 2 - 2.5 hours. MLB wants the ad revenue anyway and changes simply wont be made there, so I wasn't going to suggest that.
Re: managers slowly coming out on a replay
Before replay, they'd just come out and argue and scream for a while, so I'm really not sure that there's any time difference as far as that goes. The only issue is when the reply officials in New York drag on forever and ever trying to make a decision.
Re: umpires
As far as the world knows, there's no accountability with the umpires, since we never hear anything. If there is already accountability, MLB needs to tell fans. If not, they need to make umps accountable.
A side note: recently there were several sports site articles detailing time changes the Atlantic League made over a weekend (since they don't have a player's union slowing them down). The limited timeouts and one-minute warmup requests I simply took from what they did.
