Actually, no. His use of commas is correct. He surrounds the “in college” with commas because they hold no direct weight on the outcome of the sentence.
The sentence reads the same with or without the “in college” reference. The “in college” addition was purely put in to inform the reader of where he did his drinking, but to leave it out doesn’t change the sentence at all.
If the “in college” was important and changed the outcome or structure of the sentence in any way, then Brian would have been correct in starting the sentence that way.
EX: “When I used to drink while in college”..
This would mean that the ONLY place Brian used to drink was in college, thus an important piece of his sentence.

Thanks.

The liar liar pants on fire is always the defense used to refute a witness immediately after the attack their credibility.

Clemens cheated. The names in the report are the ones that Mitchell’s team felt they had proof on. They just didn’t have proof on the others – like Pudge Rodriguez,…

Here’s a good question – right now what does Roger have to lose LYING about not taking steroids? He’s not in court so there is no perjury.

I feel bad about Pettite – I’d like to think he wasn’t a hardcore user like Clemens and just did it to recoup as the report suggested. I’d also like to think that his statement is just to hold time while he decides whether he will fess up to a small mistake or take the Clemens route.

Brian is just a bit confused. He’s throwing words out there that he probably doesn’t even know the meaning of. Roger denied the use of any PEDs, however, Brian is just like any other Red Sox fan…a moron.

Brian, since you attained an English degree, wouldn’t you know how to use commas correctly? Shouldn’t it be “Back when I was drinking in college, I attained…”

Thanks for your abrupt response.
