I know we discussed it ad nauseum during the playoffs, but I have to mention one last thing about video review (probably the last time before next season).
Instant replay/replay review/video review, whatever you want to call it, it's been a success. It's been around for a little more than a season (beginning in September of 2008), and has only been used for disputed homeruns. Of 65 disputed calls since then, 22 have been overturned (34%)*. 34% may not seem like much, but it is. Homeruns can completely change a game. To think that umpires have been blowing a third of (disputed) homerun calls in the past is disturbing.
Unfortunately, general managers didn't have enough poor umpiring in the playoffs, so video review will remain limited to homeruns next year. If Tim McClelland's atrocious non-call in the ALCS wasn't bad enough, I shudder to think what kind of call will motivate expanded video review.
