I keep seeing it falsely reported that Matthews walked on at USC weighing 161 pounds. That is flat out incorrect. It appears as though the latest he weighed that little was at the start of his senior year of high school. Matthews himself states that he was 6'1" 166 his junior year or high school. He walked on to USC at 228 and was sitting at 220 following his first camp there.

The article currently on the front page of this site also lists his current weight as a minor issue. Stating his present weight as 240 lbs, the article notes his size as a con. "Matthews has the height part covered at 6-feet, 3-inches. But he is way off on the weight part at just 240 pounds."
Good news to report on that front as well. Matthews weighed in for the start of his first Packers minicamp at 250 lbs and says he thinks he'll aim for 255 in the next year.

All in all size not only should not be a concern for Matthews, it should actually be looked at as a strength. He's built extremely strong, (just ask new teammate Quinn Johnson) and has defensive back-like quickness to go with LB size and power.
