As someone who has had the priviledge of coaching dozens of 17-18 players over the years who have gone on to various colleges/universities and professional baseball...I'd like to say that the MSABC Nomination Process is no better or worse than some others I have seen.
As an associate scout for the Houston Astros for the past 15 years, I can tell you that some of the best players (with the highest ceilings) haven't even been noticed yet.
Bear does alot of homework. He sees lots of players and speaks to many people. He and I have had our differences in the past, but his son played in our summer program several years ago...and I know he knows what a good player looks like.
These lists are next to worthless in my opinion. No one knows why certain kids are nominated and others are not. It happens and there is nothing we can do about it...other than starting our own lists, full of players who are placed their by our biases and favoritism.
