If you draft a 5-7" 18 year old draft eligible Connor Brown in the 6th round 156th overall coming off a 53 point season and 2 years later he is leading the OHL in scoring with 128 points and now a productive NHLer that is
good drafting and scouting.
If you draft a 20 year old Adams Brooks in the 4th round when he has just put up 120 points and leads the WHL in scoring then anyone on this board could make that pick simply based on drafting BPA by ranking current CHL scoring leaders.
Many teams prefer to sign these overagers as "free wallets" that have been passed over in previous drafts and not use draft picks on them preferring to invest selections into 1st time eligible.
If you do use a valuable draft pick on an overager he better amount to something to validate the use of drafting verses UFA signing him and drafting others that can't be signed but need to be drafting to obtain their rights.
That also factors into the asset management discussion because you could potentially have both in your prospect pool.
