Primer: Scouting scale and prospect grade scale

Description of 20/80 scout scale:
The Scouting Scale works from 20-80, with 50 being Major League Average. The scale operates loosely on a bell curve, so the further you move from 50 the fewer grades you'll find among ML players (e.g. Justin Verlander's fastball, Ichiro Suzuki's arm strength, Mark Reynold's power and Albert Pujols' hit tool would all be 80 grade). A 60 grade is sometimes referred to as plus and a 70 grade is sometimes referred to as plus-plus.

Scout to prospect grading scale with descriptions:
66 and over / A+ / Potential top prospect in baseball; potential generational talent
63-65 / A / Elite prospect; perennial all-star candidate
59-62 / A- / Top tier prospect; above-average first division starter; front end starter
55-58 / B+ / Good prospect; first division starter; mid-rotation starter; top tier reliever
51-55 / B / Solid prospect; second division starter; back-end starter; good relief arm
46-50 / B- / Prospect with questions; fringe starter; useful bench player or platoon; fringe reliever
40-45 / C+ / Flawed prospect; fringe bench player
35-39 / C / Significantly flawed prospect; limited utility; AAAA placeholder or injury insurance
30-34 / C- / Fringe prospect; significant hurdles to Majors
20-29 / NP / Non-prospect; organizational player

How is Joe Mahoney not considered a top prospect anywhere on this website? A 6'6" lefty first baseman that hits with raw power and has well above-average fielding skills, Mahoney should be tops on the prospect list. Try actually going to a minor league game to see these players instead of reading about them or judging them based on stats.

Nick Faleris, who is an associate scout for an NL team and does a great deal of ground work, wrote the following on Mahoney:

Joe Mahoney is a bat-first corner defender likely to end-up at first base or designated hitter, full time. He has some length to his swing, a not-insignificant leak entering his weight transfer and a moderate to heavy backside collapse, depending on the at bat. Prognosis? It's unlikely contact will be Mahoney's strong suit, and he could be quickly exposed at the Major League level, if not Triple-A. He projects as a bench bat or Four-A player.

I appreciate the insight but I would take Mahoney's potential over Xavier Avery any day. Physical ability aside, there are just some guys that "get it" and some that don't. Don't get me wrong, I hope they both pan out, but when AA fielding coaches needed to spray paint an "X" in CF to show Avery where to stand, I'm not holding my breath.
