I think it would be interesting to rate draftees also by sum of skill points - either guards', center's or all together for SFs.
My main trainee for example had all Respectables in five guard skills and an Average in JR, but had "only" 6k wage because of Pitiful RB (RB boosts salaries on rookies like no other skill). Sum of his 6 outside skills is 73 now (he just turned 21).
