I don't know that I've seen anyone who is giddy about them. I feel like most people are excited about adding depth, size, and experience to a very young and unproven WR corps.
Were you excited about he prospect of landing Flemming? He's clocked a 4.45. Neyor runs a 4.49, so pretty comparable. And Sark wanted him, so that's good enough for me.
Banks runs a 4.52, but he's 6'4" 215lbs. We're not going to be asking him to take the top off a defense, and we currently don't have a starting caliber WR with his body type. Coleman could become that, with the speed to burn, but he isn't there yet.
