First, Moulds didn't miss 3 games last season. He only missed one game.
Second, Lloyd had nine 20+ yard catches and three 40+ yard catches last season. Moulds only had five 20+ and one 40+ catches. Lloyd YPC was 15.3 and Moulds was 10.1. It's debatable whether number of catches is more important than YPC.
Third, it may sound impossible, the 49ers QBs actually played much worse than Holcomb and Losman last season.
QB ratings:
Alex Smith: 40.8 (7 starts)
Ken Dorsey: 66.9 (3 starts)
Tim Rattay: 70.3 (4 starts)
Cody Pickett: 28.3 (2 starts)
Holcomb: 85.6 (8 starts)
Losman: 64.9 (8 starts)
Fourth, this is just a suggestion, it has nothing to do with "gloss over". Marv may even have no chance to sign Lloyd if 49ers gives him a quality tender.
