It's been discussed in some other threads, but despite an unbelievable amount of public action on the Colts, the books are still reluctant to move their lines. The juice moved pretty heavily in the last 12 hours, which sucks since I bet the Titans before that, but that's only because they're getting 75% action on the Colts and can afford to move this INELASTIC line even more for their benefit. No offense to those who bet the Colts for entertainment.
