I don't disagree with any of this besides a future third looking good next year. Can't say I think Edmonds's value is that low. Benjamin and Ward could chip into his time, sure, but that's unlikely if they draft somebody. Eno Benjamin is a seventh-rounder and Ward is a UDFA. Neither have size/speed score advantages over Edmonds, and played behind him last year, so...
Anyway, enough on my end regarding Edmonds. I'm just explaining the thought process behind holding one particular guy in one particular instance. Mike Davis falls into this same category, IMO. You might, however, have been able to get something last year for Davis come deadline time, which would make this all moot. But acquiring him now for Mack? No brainer.
