I am not sure if any of these sites let you do it but it would be cool if you could link your drafts year to year, seeing how everything played out. In this case you would get to actually use those picks you traded for and compare how it worked out vs what the team did.

I love getting future draft compensation. It always feels like a freebie, since I only trade back when I either don't like any of the options or I can definitely still get a guy I like.

It's always a tough call. I had one draft I did where JJ McCarthy fell to 31 and I didn't like the trade offers (even though they were good they were all 2025 draft pick based, what fun is that when I am doing a 2024 mock) so I just took him. I figured he can back up and if he is solid maybe the 49ers can move on from Brock instead of paying him 40M a year and restart their cheap QB window. I don't think they would do that but it made sense to me.
