I have been at this for over 20 yrs and I cant ever remember the favs coming in like this week after week...........if I were a bookie I would be getting pissed at the linesmakers.........dont the dogs have to be covering sometime????
Naw, it's not the spreads being too low. It's not like these favs are covering the spread by 1 or 2 points. Most of them are romping. All it is is random happenstance. In 20 years you are going to have one or two like this...though this is truly extreme.
You flip a coin 100 times you'll be within 5 of 50 heads coming up something like 18 times in 20...but you will still get the odd extreme, and that's all this year is.
