proxies are a good tool. however, depending on how the draft is going, proxies can get in the way of good drafting sometimes. i know a few times i set proxies, but when i checked in to see what was going on, i had to change them due to a run on certain positions.
although i'd like to get to my next pick as quickly as possible, i can understand why some guys might actually want to make the best possible pick for his team at that time.
with all of that said, i guess i should have just set up proxies for the entire draft. this may be my worst draft in any fantasy type league i've ever had.
