week 5 teasers and colts/niners

So ive been betting for years and Ive never bet teasers ive always thought they were dumb. But then last week i saw a few games that would be good teased and ended up fluking out on an 8 team teaser. Anyway this week i dont like nearly as many games, these are the ones i do.

Indy -8
Denver -1
Carolina- line not up but it will be close to a pick em

Anyone want to add some "locks" including overs and unders. Parlays there are no locks but teasers there are ones pretty damn close since vegas is so good at making spreads.

Also please talk about the colts niners game set at -14. I broke even in weeks one and two in huge bets on the eagles/niners and colts/browns, so I definately dont want to go too big on this one until in convince myself its as close to for sure as it gets.
