I play with a kid now that had scouts looking at him his freshman year, he started on varsity over a senior. Everyone on the team knows hes going places. IF he gets a full ride because unfortunately his family cant afford college.
Some schools though are known for putting out quality players. Around here there is a Catholic school that has put 4-5 into the NFL in the past few years. They have also put out 3-4 players into the MLB.
Emmitt Smith came out of a rival high school literally 15 blocks down the road as well.
