Awesome move just for a 5th rounder!
Better field position to start with. As a reciever, he seems to be durable (perhaps due to his "soft"/finesse style of play).
Crabtree, Morgan, Ginn/Hill (I'll assume Brandon Jones needs to prove he has hands AND can stay on the field) makes for some speedy receivers to complement Vernon and even Gore going out of the backfield.
Nice work to get bodies that will help out Alex.
Next, we need to get that OL help, as well.
