Well , from my exp..... home visits are nice... and as previously stated the scout is gathering more information.
A few things I have asked... age of the scout , how many players he has had drafted, how long he has been a scout, the size of his territory. How did son grade out... where does he see him in their org?
IF you are getting info from MLB you are likely in the top 300 HS players.... turning in all medical records , giving a urine sample, getting a MRI or CT scan.
Look at this from the scouts point of view... He has a territory he covers, sometimes he finds the player , sometimes the club tells him to go scout a player. The scout has to turn in the charts, numbers, videos, home visits , impressions etc... IF the Dir of scouting, asst. GM's, national cross checkers are coming in you may just get drafted high enough to take the money. If it's a area scout he may love you, and he may never grace the draft board meeting room either.
Do some research, most of the time the top top HS players will go, the money is too good.... or a HS player that's a project and will sign on the cheap....... but when it comes down to it... teams will take, and there's a trend to take, proven college players that fill the teams needs.... less risk, less money, ready to hit sooner....
Don't get me wrong, we had a blast with draft stuff.... great times, meeting nice people... but factor in the returning players, free agents, rule 5 players, foreign players , college players, you better be ready to go take someone's job in spring training.... Oh and once you get there, it's new set of opinions ... scouts moved on to next years draft.
Tough road for HS players that don't go in the top 3-4 rounds.....
Enjoy... good luck
