Not ABSOLUTELY, especially among guards. Along with the aforementioned Pullen, Battle, Jackson, and Brooks,
Jimmer Fredette, Jordan Taylor, Chris Warren, Andrew Goudelock, Shelvin Mack, Randy Culpepper are all 3 *'s and all good enough to play anywhere in country. Players do slip through the cracks.
Bigs? Pfft, pretty much as a rule, the highest rated out of HS are the best in college.
good distinction. hadn't thought of that. most of the high rated bigs are gone after 1 or 2 years in college
bigs are easier to scout than guards, no question. plus there are many, many more guards than bigs (bell curvey stuff).
i'd also add that, imo, the most consistently overrated type of players (in terms of college production) are tall, thinnish wings and/or hybrid forwards.
