Last two seasons i gave the 19yo's a try. Scouted only them. Sadly i didnt get anything even worth mentioning.
I did the exact same thing last season and got a HOF 19 yr old. It seemed like everyone put the 19yr olds below the 18 yr olds....and boom....got a 4 ball 5 ball 19yr old at pick 12....got lucky for sure.
