Wait, what?
Now that's definitely a case of over-the-top criticism.
Apparently none of the following Free Agent signings by Shero worked out:
Jarkko Ruutu
Petr Sykora
Ty Conklin
Ruslan Fedotenko
Matt Cooke
Aaron Asham
Yeah, none of those guys worked out at all!
That's not even counting a variety of other free agents such as Mark Eaton or Zbynek Michalek who had ups and downs with the team, nor does it count any of the undrafted free agent signings (including current HFBoards favorite Jayson Megna).
Nope, in 8 years with the team, Paul Martin is the only free agent who has worked out.
See, this is the sort of hyperbole that undermines all your other arguments. It makes you look like someone who turns a blind eye to anything positive just so you can accentuate the negative, which, in turn, makes it seem like you're probably using hyperbole in all of your claims, not just some of them. Note: that applies to both sides of the argument, but the quoted statement took it to an extreme.
