I remember looking at Isaac Bruce's stats once and being totally confused about how he didn't make the Pro Bowl in his second season:
119 catches, 1781 receiving yards, 13 TDs.
And he was St. Louis' only consistently dangerous offensive player. They didn't have another player with even 500 receiving yards that year, and he had Chris Miller and Mark Rypien throwing to him. Gotta be one of the most underrated great individual years of all time.
