after three seasons I am assuming you only get trade offers during the draft since I have gotten none in 3 years .... wish there was a way to put someone on the trading block and get emailed offers for them ... if this happens I might be doing something wrong

There is a way to put players on the trade block and get offers via email during the season - go to the trade page and hover your mouse over the orange button that says Trading Help. This will show you that you can add a player to your trade block by clicking the "blocks icon" in the row with his name on it and it will also tell you how you can shop players immediately as well.

thanks
