Now, I'll admit I don't know much about sports betting and I'm sure this post will illustrate that, but I just can't see how Minnessota is not a lock.

So, will someone please explain to me how Detroit can possibly be a good play, let alone a LOCK?

Short answer (i'll post more later):

#1 - there's no such thing as a sure thing, aka a lock, in sports betting
#2 - if a favorite line looks like a lock (to a casual fan) you're almost always wrong. The sports books don't generally give away free money, they set the lines that take all the factors in to consideration.
