Picking Dupree is no different from picking Decastro when he fell in the draft - Dupree was higher rated on the Steelers board than any of the remaining DB's. I expect it wasn't even close between him and Jones.
Dupree being at a position of great need is just icing on the cake.
There are plenty of good DB prospects left including my favorite - Ronald Darby who could last till the Steelers pick in the 2ND.
Here's a good summary of Dupree from Walter Football --
"
Despite spending the past few seasons as one of the best defensive players in the SEC, Dupree went under the radar playing at Kentucky. He is a big, fast, edge rusher who can be a force on the edge.
Dupree became an every-down player in 2012 and had an impressive debut. The sophomore totaled 91 tackles with 12.5 tackles for a loss, 6.5 sacks and a pass batted. Dupree stayed consistent in his production as a junior with 61 tackles, nine tackles for a loss, two forced fumbles, one pass broken up and seven sacks.
In 2014, Dupree recorded 74 tackles with 11.5 tackles for a loss, one pass batted, one interception, two forced fumbles and 7.5 sacks. He was much more disruptive than the numbers illustrate, and his sack production was hurt by going against eight read-option offenses. Even though Dupree didn't have a huge stat line, he was very good against Florida as he caused a lot of disruption with pressure. Dupree had a huge pick-six against South Carolina in Kentucky's seven-point upset win. The Wildcats also played from behind quite a bit in the second half of the year, and that led to fewer pass-rushing opportunities for Dupree as teams ran the ball against Kentucky.
For the NFL, Dupree has the speed and strength to be a tough battle for offensive tackles. Dupree would be a star of the all-looks team with his body type. As a pass-rusher, he can burn tackles with a speed rush yet also is strong enough to fight them off with his hands. Dupree can shed blocks and win with a bull rush as well. He could use more refinement with his pass-rushing moves, but he has the potential to be a double-digit sack producer as a pro. Dupree is also a good run-defender. He is strong at the point of attack and is able to maintain his gap. Furthermore, Dupree pursues well and has a good motor.
