This makes me wonder:
Who is the most random, inconspicuous, insignificant Shark you can think of that left a significant negative impression on you. Not the obvious ultra-train-wreck guys. The ones where it's not immediately at the forefront of your mind that they were actually on the team, but once the memory clicks into place it just opens up the floodgates of bad vibes.
I'd say Adam Burish, but he fits the "train wreck" description.
