And BPA is much harder to determine in baseball.
So I think need plays a part, not in the sense of the ML team, but in the sense of the organization.
You want to maintain balance so you don't retard the development of your "real" prospects.
So I see less as "we want this position" than "we know our organizational strengths and weaknesses."
Phillies seem to do well with pitchers and IFs in LA, so they may look in the draft more toward OFs and power.
Landing the top LA pitcher two years in a row, as well as finding Sixto, may make HS pitchers relatively less attractive this year.
I think the strongest determinant of BPA is organizational philosophy, Klentak seems to put more emphasis on baseball skills rather than raw skills.
So the Phillies may rate players differently than some teams (and BA which is raw skill oriented).
Even later in the draft, Phillies seem to like hitters with good plate discipline for the most part, and pitchers with FB command.
Last year Haseley certainly fit the team philosophy, even though they really didn't need to draft another OF.
So it may end up as a combination of "need" and "philosophy" determining how they rank players.
