Will the Lakers draft for need? They need a point guard, and trading up to the top five would get them a chance at the only decent ones in this draft. If they hold on to the pick, then they go to the second alternative and draft the best guy available, such as May, Graham, Villanueva, or some comparable guy to do some low post scoring and rebounding.
The pickin's in this draft for anyone looking for immediate help taper off after about eight or nine, so just a thought but any team picking in those spots would wait for a somewhat desparate team to come calling with the best offer.
If the Lakers made the offer, Portland could wait to see if something better comes along prior to making any rash decision this far before they draft.
