It's almost impossible to find a scouting report projecting a guy as a 1 or 2 "without a doubt", but depending on the guy they will give a higher floor and higher ceiling.
If you do a quick search for "scouting reports" for Webster, Barnes and Owens, the more current ones usually give Webster a #3, #4 floor with a #2 ceiling, Barnes a #3 floor with a #2 ceiling, and Owens a #3 floor with a #1 ceiling. What i can't find again are John Sickel's grade assignments for the three of them (or any other prospect for that matter) which were posted to over the monster. Sickels gives Barnes and Owens a B+ while Webster gets a B but makes the comment that the grade is liable to improve if he can improve his command a bit more.
