Broaddus Breakdown (viewed Notre Dame, Florida State, Clemson and Senior Bowl games): Was the starter at left tackle for the Eagles but showed the ability to play guard and both tackle spots in the Senior Bowl. … Shows some initial quickness off the snap in the running game and in pass protection. Is able to adjust as he works away from the line. Doesn’t have the smoothness of Tyron Smith or Nate Solder but is able to get himself into position to make the block. … Has better punch in the running game than he does in pass protection. Smith has the best punch of the tackles I have seen. Castonzo tends to place his hands on the defender and tries to control him with upper body strength or muscle him. … If he has a fault in pass protection, it is that he will get overextended and have too much weight going forward, allowing separation with his man. When he does keep his weight back, he can move his feet to slide and adjust. … Did a nice job of passing a twist stunt against Florida State. The struggle that he did have in the FSU game was when Brandon Jenkins used an inside spin move to gain some pressure. This happened two different times in the contest and Castonzo was not able to adjust quickly enough to keep him from the pressure. … Shield and position run blocker. Is not going to drive his man out of the hole but will come off the ball, fit and work his feet to sustain. … Did a nice job of carrying Da’Quan Bowers down the line and keeping his body between the defender and the ball. Was asked two different times to get to the outside on a sweep but was unable to stay on his feet to secure the block. Not a clumsy athlete but looked awkward on those plays in space. … Liked how he was able to play two different positions in the Senior Bowl. Did not look as a throwaway as a guard. If he had to fill in, I don’t think there would be an issue there. … There is an outstanding history of offensive linemen from Boston College, so he will be a top consideraton. Of all the tackles I have viewed, I like him behind Tyron Smith and ahead of Solder and Gabe Carimi.
