I would be extremely careful and go with your gut instinct. The online sports betting sites advertise offers that sound great, but usually have many conditions. I would not depend on them giving you anything. I would pick one for its convenience or just because you like the site. I picked one that gave me the option of going to my local casino and placing a bet if I so desire. I would make a bet(s) based on what you feel most comfortable making and not on some advertised promise. That is what I have done. Rewards almost always have a short fuse. That is what sucks people into signing-up. I say didn't fall for that stuff. Just my opinion and good luck if you decide to bet on the SB. I took the Money Line on the Chiefs, which pays more than double.
