Trading back does seem to be a viable option. I use the free mock draft generator at profootballnetwork which enables trades and I am usually pretty happy when I trade back in those scenarios.
I use it too (it’s addicting in fast mode). But I question their rankings of players and valuation of picks. I seem to almost hit the motherload with both.
for instance last draft I traded down twice to 20. It netted me the following:
20. Ja’marr chase, wr LSU
49. Asante samuel jr, CB FSU
51. Alim Mcneill, dt NCST
52. Landon Dickerson, C Alabama
79. Dylan Moses, LB Alabama
82. Quinn meirnerz, C Wis-Whitewater
242. Jonathan Cooper, edge Ohio state
seems kinda rich
