DT Marcus Harrison – ArkansasThe numbers: 6-3, 317 pounds, 5.06 seconds in the 40-yard dash, 26 bench-press reps at 225 pounds. The skinny: Nobody can deny the fact that Harrison is oozing with talent and potential, but a history of injuries and some off-the-field issues hurt his stock in the draft significantly. He has the ability to play both nose tackle and the three-technique, but expect him to play the nose in Chicago and work into the rotation next to Pro Bowler Tommie Harris. The analysis: The Bears went with high-character guys across the board with their first three selections, but they deviated from that philosophy significantly because there will be inevitable comparisons between Harrison and the talented-but-troubled Tank Johnson. However, D-tackle is perhaps the biggest need position for this team on defense, so he'll get a chance to play right away.
