Leave the coring the way it is, this is VERY standard scoring and doesn't inflate the QB's too highly. In order for a qb to get 10 points they need to throw 200 yards, were a running back only need 100, that's fair, also take into account the -2 for int's , a 4 int game will cost you 8 points (a td and 50 yards)
the scoring is fine!
