Um no not right we have a semi pro football leauge in SoCal- I played for the LA Scorpions- lascorpionfootball.com some of the teams on the league were paid(notmuch)
Minor League if u will
Minor league, amateur, sandlot, etc....
It's either pro, or it aint.
"semi pro" would be College-div 1-A, if anything was.
