I'm surprised that the home favorites are doing so badly ATS, given that the extra innings rule benefits the home team big time. However, I know you're saying home FAVORITES, so yes, I will agree that the rule does help the worse teams level the playing field. Interesting.
Funny that your post came on the heels of my winning a home favorite (albeit a very small favorite).
Anyway, no MLB picks today. All NBA for me this evening.
