Sounds like he's channelling the spirit of Joe Mack...the spirit, or the ineptitude...one of the two.
Seriously, that comment sounds like he's trying to sidetrack the fact that he lost a 2nd round pick. It's like "aw, the second round picks were **** anyway, so I thought I'd just throw this in for good measure". I'm losing faith in this guy quick. He's trying to make trades just to appease the fans. "Oh look everyone...he's doing something...he got rid of Buck (for a shitty receiver) and now he got us a second rate Olineman...WOOHOO...he's teh Aw3s0mE!!!ONE1111". So far, the only person he's brought in that seems to be worth ANYTHING is Kelly. Foster, Boltus, Sims-Walker, DeAngelis...all crap. And how many NFL cuts stuck around, other then Sims-Walker?
To be fair, I think your expectations of what he should be doing mid-season are a little high. I would say the best thing Walters has done is purge some of the useless assets our team has to set us up in a better position to compete next year. His goal was never to compete seriously this year.
Even though Foster hasn't done much, its stuff like getting a young Canadian receiver for an old broken QB that Joe Mack would've never done.
