Alright so how I see it is view it like a trade. First you need to look at and try to figure out who is keeping who, so you can take a look at who might be in the first round, and who might be in the first round at the 8th pick. Then attach names to the trade so you can look at it more clearly.
For example, would you rather have Lev Bell and a 20th round pick OR Keenan Allen (purely and example of who MIGHT be there) and Jerrick McKinnon?
Or would you rather have Lev Bell and a 4th round pick or Hopkins and Devonta Freeman (again, just an example of who MIGHT be there)
Once you start attaching names to these rounds, it makes it easier to start eliminating options.
Personally, I LOVE the value of McKinnon and believe you can still build a very solid roster with him. I mean, especially since this is a 1 offensive keeper league man, your draft will still be loaded with good players. That’s just me though dude, attach names to draft picks so you can make your own decision! Good luck man.
