12 teams 35 roster spots
Too early for me to value this type of pick trade personally. I won't be through player evals until March and then things will change again with the NFL draft.
In a vacuum I like the value of that group of 4 over 1.06, 1.07............ for a 35 roster slot league. The reverse would be true in smaller leagues.
However, I have had really good luck drafting in that middle of the first area which would make me hesitant even if I value the 4 picks higher. It seems the occasional uber-talented prospect can fall into that range if the perception of landing spot is poor and or minor camp injuries...........Beckham comes to mind as one I was fortunate to have fall there in a number of leagues.
