Definitely question marks for Exum and that next tier.
But, assuming Saric is also as good as advertised, it seems he's probably the last pick (at #9) before you drop down to another tier of player with even more question marks (or less upside).
A team looking for a PG who's not wild about Ennis might try to move up into Smart's range.
A team looking for a PF who's not a typical stretch 4 might try to move up into Randle's range.
It'll take the right buyer for Ainge to sell the pick. It's quite possible there won't be a blockbuster offer, as Pho says.
Maybe not a blockbuster deal initially, but perhaps something to set the stage for the alluded to "fireworks".
Maybe Philly or Phoenix become enamored with one of Smart/ Randle/Gordon/ Vonleh.
Philly has the 10th pick and second round picks up the ying-yang.
Maybe our pick for their 10th, 32nd, 39th and 47th or their 10th and take away the protection of their first that we have next year.
Phoenix could give us their 14th, 18th and 27th pick, if they love one of the guys we could pick for them.
We could then use our multitude of picks to do a blockbuster.
