Three is a magic number. Those of us who grew up on "Schoolhouse Rock" already know that.
Others have had to find out for themselves. Washington Redskins fans learned very quickly Sunday, when rookie quarterback Robert Griffin III completed his first eight passes as a pro, including an 88-yard touchdown to Pierre Garcon.
Overall, RG3 completed 19 of 26 passes for 320 yards and two touchdowns with no interceptions for a passer rating of 139.9. He also gained 42 yards rushing.
Clippers fans learned the power of 3 last season when all-star point guard Chris Paul came aboard and immediately helped the team become a contender in the west. Paul is frequently referred to by the nickname CP3 -- his father and brother both have the initials CP, plus he wears No. 3 on his jersey.
