What will scare teams is that he is not actually 6'-0" tall.
I like Shipley, but there is no reason to reach for this guy. He will be around in the 3rd or 4th round. He is better than McGarity. That is obvious. Jones could have picked up McGarity much later in the draft that year. He really reached for a guy no other teams were interested in. Forget about the Texas connection and focus on guys that can help the team. Roy is not going to meet the unrealistic expectations of trading a 1st and 3rd, but he still helps the Cowboys. Shipley can help Dallas out of the slot, but he isn't going to be able to match what Williams does on the outside.
Let's see how Percy Harvin develops during his career. He is getting by solely on physical talent right now. He is such a great athlete, but will he become a good receiver. He still has to develop the technical aspects of the position. I like his chances, but there have been plenty of wide receivers that flashed some brilliance early only to disappear because their games did not grow.
