the grizzled veterans will tell you that 2, 3, and 7 are the basketball key #s. i have heard a middle expert say 10 is key in ncaa.
in the tourney, its very hard to tell when these kids will stop fouling. look at the illinois/nevada game. under 10 seconds to go and illinois up 11...nevada fouls and illinois covers. nba they stop fouling when down 7 or more with under 24 seconds but...in college...these guys dont always quit when you think they will.
