In fact, I wish there were MORE trades.
Started a 100 mil 20xx team and there was only 1 trade offer made to me and unless I missed it no trades completed by anyone in the league.
My last ATG league is a 140 mil league and only made 1 trade.
If you really like trading my suggestion is to play more 200 mil leagues. I cannot remember the last time I completed fewer than 3 trades and there was a ton more trade discussions.
My theory is the lower the cap the more likely someone on FA list will meet an opponents needs. Thus they see no reason to give up something to fill that need if it is preseason. Indeed, why waste time negotiating when you can just drop someone and pick up whatever you need. But with 200 mil the cream of the crop will be sitting on someone's roster. So if you want to change the chemistry of your team you gotta make some offers and negotiate. Of course I realize 200 mil is not for everyone.
