He's nuts. Welker is a machine. I bet these past 5 years are as good as any WR has ever had.
Uh, no, not even close. Welker is only #4 in WR yardage in the past 5 years, and #15 in WR TDs. In those same five years, Fitzgerald, White, and Wayne all have more yardage and more TDs. Welker has 6105/31 in 77 games. (None of the other three have more than 80 games). Jerry Rice beat that with two completely different 5-year periods (from 1985-1989 (6364/66), and from 1990 to 1994 (6911/65)), and from any 5-year period you choose prior to his injury in 1997. His best was either 1992-1996, where he went for 7305 yards and 61 TDs, or 1986-1990, where he put up 6939/76 despite a strike-shortened season. So, what did you bet?
