U can that's what I did and it went through with jets -colts trade except the picks were all WRONG....its saying the jets had the 25th pick and the colts had #2,34,and they didn't have extra second and u can't send one next yr with it because it only has 3 slots.
So seems like u have do a lot of trading just to do that one deal that got done all at once.
Just tried browns dolphins trade for landry it went through but again the browns pick was 4th rd 125 in real life its 123.
So I guess that works when controlling both teams but seems like a lot of work if u want real picks like say jets colts.
I'm trying all this at the beginning of season so u may have to sim whole season and maybe that changes the picks numbers?? But then again ud have go through all teams and force wins and loses to match their records.
