Mo Crum was a good football player. Not taking anything about from what he did on the field, but the talent or lack there of...made him look better than he was.
His senior year he had 84 tackles, 1 sack, 4.5 tackles for loss, 2INTs. The 3 force fumbles and 2 fumble recoveries were great. But overall not a extreme "this is a great player" statline.
His junior year he had a great year. 100 tackles, 10 tackles for loss, 4 sacks, 3 forced fumbles in 13 starts. So the tackles were close to on par with his senior year with the extra game, but he was in the backfield a lot more. Soph year 57 tackles, 0 sacks, 3 tackles for loss and he started all 12 games.
Dan Fox senior year he had 95 tackles, 5 tackles for loss, 1 sack, 2 INTs, and a fumble recovery. Carlo Calabrese had 93 tackles, 5.5 tackles for loss, .5 sacks, 1 forced fumble. In the "fans" eyes these were two of the most unproductive LBs and they finished top 2 in tackles in 2013, and had just about the same statline as Mo Crum.
