The Steelers do not need a nose tackle. McLendon is a good one. Do you only look at stats and PFF Ratings? 3-4 NTs are not SUPPOSED to have gaudy numbers. They are supposed to plug the gap and are a main key to a good run defense in the 3-4. The Steelers had one of the best rushing defenses in the NFL. I honestly wonder how you have a job sometimes.
Summary: I am not sure what position Smart will play at the next level but because of his ability to impact the game in a number of ways and how hard he plays on both ends, he appears to be a lottery lock. If Smart were a better shooter or true point guard, he would likely be in consideration as a top-five pick which still might happen.
Player Comparison: Tyreke Evans. There are a lot of similarities here; size, strength, ability to attack the tin, struggles with outside shooting, versatility, lack of a true position. What separates Smart from Evans is his competitive fire and effort on the defensive end. I'm not sure Smart will ever be a 20 point-per-night type of guy like Evans was during his rookie year, but I wouldn't rule it out down the road.
