they are a point where not all picks make the team.
last season I think 2 picks on PS got plucked.
plan on 1st. 2nd, and 3rd making team.
thry have one roster WC spot for a surprise prospect ( Stephenson got this slot last year).
there is no difference in expectation of a late 4th vs 5 th or 6 th on chances to make a team.
