Figure I may as well update this...
I quickly decided that I wasn't going to play TE after I learned I really can't catch and their was quite a few on the team last year. I then switched to guard but I didn't like all the stuff I had to memorize. I then went to OT and stayed their for the season, although I never played a game at it, seeing as how our O line weighed an average of 270 lbs, and I only weighed 145. I also stuck with DT, which I got a good bit of time at.
Since then, I've gotten up to 165 and a hell of a lot stronger, mildly quicker. I'm probably going to stick with OT and DT this year. I still don't envision myself playing much, if any, O but I got a decent chance at D line this year. I'm more or less just planning to get up to 175 by season and see how that works for me.
By the way, we got to the first round of playoffs this year. Our halfback also broke the school rushing record. He's going to be playing next year as well along with another equally as good HB.
Any thoughts on the bulking up side of things?
