That sounds good in principle, and this makes sense if we are evaluating the efficacy of all first round picks versus all picks in later rounds. No argument with that conclusion here.
However, it was pointed out that the median WAR for fifth overall pick, specifically, is zero, meaning half of all fifth picks in the first round end up with that or less. With such a high failure rate, is it really worth it to crash a team into the rocks, flirting with or exceeding 100 losses, and driving fan and sponsor interest in your team and the revenues attended to it way down, just to get that pick?
