Not surprised. Matthews went from 166 to 245 in like three years. That's doable, but I'm sure the roids helped him out a bit.
I took this from another site where I got into it with this retard that thought Clay Matthews could put on over 80lbs of quality size in three years (naturally) while playing football at the top college program in the country. The riods only helped a bit and we don't know for sure how much, lol.
Is there anyway a person could gain this much quality size in three years, naturally? Keep in mind that Clay was working out BEFORE he got to USC, so no newbie gains there.
