Wow, we all love Fitz, but this seems like revisionist history. In his 95 games over his 7 seasons with the Cardinals,
Boldin averaged 89 touches, 1104 yards, and 6.3 TDs per year. In his first six seasons (92 games),
Fitz averaged 90 touches, 1187 yards, and 9.7 TDs per year.
Boldin's style and toughness led to more injuries, but on a per-16-games basis, Boldin averaged 105 touches, 1302 yards, and 7 TDs, while Fitz averaged 94 touches, 1234 yards, and 10 TDs.
In his 202 career games, Boldin reached 13779 yards, 82 TDs, and a Super Bowl ring. In his first 202 games, Fitz had 14389 yards and 104 TDs.
No argument that Fitz was better, and missing about 10% of his games hurts Boldin's case, but I don't think the margin is as wide as you portray, especially during the time they were both with the Cardinals.
