You hope that you can find a diamond in the rough, but there's a whole lot of rough out there.
Sure. But - and this has always been my biggest criticism of Chambers - his under-the-radar recruits just haven't panned out. Obviously, it's not a good strategy to aim for 2-star players, but Ed DeChellis at least turned a number of those guys into key pieces, either through development or just picking the right guys. Players like Andrew Jones, David Jackson, Stanley Pringle, Cam Woodyard, Jermaine Marshall, and Ross Travis were middling prospects at best but turned out to be key contributors on solid teams.
Pat Chambers' list of less-heralded players is Akosa Madugbunam, Donovon Jack, Isaiah Washington, Julian Moore, Graham Woodward, and Davis Zemgulis. That's...not a great group.
Ideally, you'd have a coach who was as good at getting top prospects as Chambers and good at identifying talent as DeChellis. And I don't think it has to be such an either/or.
