If you like INDY to win the game, you should bet the ML. Currently around +270 or so.
As for the teaser issue, this entire thread and all of it's contents is based around some pretty strict guidelines. You can find those in Akillies posts on page 1. You can also look up his thread of a similar name from last year as well and reference the first page of that one as well if you are interested.
Personally, I think this teaser play is a winner, but good luck to you with the 2 TD's you are getting in your teaser.
