Pretty much, I was never really all THAT big. I was pretty skinny, but I was big enough to hold my own on the line.
Not to mention I was actually decently fast and I have a really good arm thanks to baseball, so I tried out for QB when I went to high school and wound up as the second string guy, and I moved into the starting spot halfway through the year.
I don't play anymore though since I want to focus on baseball.
