I'm in favor of the ban. I know there's a lot of excitement when a close play happens at home, but player safety is more important than any single close play. In fact, I wish they would extend it to ban spiking the fielder at second base on a potential double play ball. Tigers lost Infante for a month last year on a questionable play at second. I don't think there's any reason for it.
Takeout slides are tough to judge. Can't fault runners for sliding into the bag, but I would advocate for a ban that includes heavy penalties for sliding into a fielder who's on one side of it or the other -- or for sliding late over the bag into a fielder (Matt Holliday comes to mind). 99 percent of the time it's a you know it when you see it thing, so wouldn't be a huge change/problem.
