home field advantage

when capping nfl games....how many points do you usually give the home team or give the road team i should say? college ftbl? college bsketball? thx

i read sometime ago that nfl hfa is really only worth about 2.3 points, in college hoops and football since the talent is so varied, a good team, hfa is more that a poor team, put it this way, the worst a team is the less the value of hfa is. generally good teams in college hoops can be as high as 7 points. nba is around 3 to 5 points. go back and look at prior season result in college hoops when teams play interconference late in the season, youll see the line swing about 8 to 9 points in almost back to back games.
