What about FA Ricky Proehl as our 4th WR? He'd come way way cheaper than Moulds (at his age Proehl would probably accept a 1-year deal). Last year at the age of 37 he caught 25 catches for 441 yards for an amazing (for a 37-year old) 17.6 ypc. He keeps himself in great shape, has great hands, is an excellent route runner, and makes clutch catch after clutch catch when his team needs some crucial yards or a 1st-down. He's not the flashiest guy and he's used to being a complementary guy having almost always played in the shadow of star WR's so the other team's secondary just ignores him and he's allowed to just wander downfield virtually unimpeded.
