Point Spread Records Help

[brandonboyle1]

Hey guys I was wondering if anyone knew where to go to find info on records of point spreads(CFB and NFL). For example in the past 15 years what the record is for teams favored by 3.5pts and of those winners how many were home and how many were away. I have been searching online and haven't been able to find anything. Any help would be appreciated, I would like to create a database for stats like this covering the past 15-20 years.
