Depends on how they handle themselves when I deal with them. For example, this one guy this year kept offering me junk for Randy Johnson. Even offered Burnitz for RJ straight up the day of RJ's perfect game. At first, I just simply rejected them, no explanation was needed. Finally I grew bored and started counter offering with my Webb for his Helton. Needless to say that he left me alone for awhile after that. Now this week he offered Helton for RJ. Now that one I did politely decline and explained that whip/era are my two worst catagories and I couldn't afford to deal RJ right now.
Now if a team makes me a fair offer and I decline, I do try to explain why.
Yes doctor, I am sick.
Sick of those who are spineless.
Sick of those who feel self-entitled.
Sick of those who are hypocrites.
Yes doctor, an army is forming.
Yes doctor, there will be a war.
Yes doctor, there will be blood.....
