one big lesson to learn is that we should never consider the players already at the position, proven or not, given a a chance or not, as a deterrent to drafting that position.
my reason for not wanting Luke was because we had already used a good number of picks on that position.
just because we have guys we may like at a position who have yet to be given what we consider to be a real opportunity doesn't mean that we won't or shouldn't invest a high pick. you draft who you think could have the biggest positive impact on your team regardless of who is already there...esp. early. you may have potential at a position, but if you see a player you think could be great...not guaranteed (because there are no sure things or guaranteed things in the draft), but who could be great then you take them.
