FYI he leads the league this year in penalties by an OLman. Giacommini is 2nd behind him, so the whole "1 penalty thing" is WAY off.
I personally think he was getting a lot of those false starts because he was playing injured, and he needed the jump, but if he could stay healthy, he'll be a good one.
Actually, I wouldn't say it's that far off. From what I can tell, before this week, he was TIED for first overall with two other offensive lineman, with 9 penalties (6 false starts, 3 holds) for a total of 60 yards. I can't remember if he was actually able to make it back for the season opener or not, but I'm thinking he's started every game this year. That averages out to about 1.1 penalties a game. I'll take it. It's not perfect, but nobody is. And like you said, I think a lot of it has had to do with playing injured and not quite being up to speed on things.
Here are the penalty statistics for the year so far. I am assuming this is through the first 8 weeks:http://www.footballdb.com/penalties-player.html
