That is true. Dominant receivers don't equate to Super Bowls. Great QBs, a great running game, and a great Defense normally do.
If look back at the past winners since 2000. Most had a dominant Defense (PIT, NYG, NE, TB, BAL), a great QB (PIT, NYG, IND, NE), and a solid running game (NYG, IND, PIT, NE, BAL). Hell, PIT won last year with their leading receiver having 1,009 yards and leading rusher having 791 yards, but had a sick Defense.
I also think Hester will crack the top 30.
