So basically what you're saying is we are overdue for a team trailing 3-1 to come back and win!
We've been upgraded to 8.6% now. But teams down 3-1 have had a rough patch, they're 1 out of their last 16 finishing the job. (Tampa 2011 first round against Pittsburgh) Actually, more teams have tied up 3-0 series than have won from 3-1. During that time period, obviously.
