I read into it as being two things:
+Rebuilding through the draft means he's more then willing to dump some veteran guys this year (watchout Tony)
+No fear of packaging draft picks consisting of the current draft year as well as future draft picks
I really think that Pioli is savvy enough that if he wants to trade down he'll find a way to trade down. I for one wouldn't be suprised if a scenario such as him packaging this years pick with another pick from the latter rounds in next years draft (if he had too) if he wanted to trade down to a more favorable position to help the team through FA to preserve some cap space in near future to further the teams quality with free agents rather then unproven rookies.
Just a thought
