had to have been lol. i'm not sure how he could have played with all these players while they were playing at their best. i've been here 9 years and haven't seen 3/4 of these people play at their best. To put me, guyfawkes, antidote, STIFFY??, shini?? (years ago) etc. at their best below a lot of the other names listed is comical haha.
