my 2 cents, fcp is best in d2 & d3, man in d1 for the high end teams, although if I was going to try to win every year with a D prestige d1 school, I might pick fcp too, the reason I don't think fcp works at the high end of d1, you can no longer year in and year out recruit 12 man teams full of ath / sp / def. that still have enough core power to win a national title - a good result from the change to recruit generation that I so oppose - which you often don't hear from me. Also, this is somewhat real life, d2/d3 schools are more likely to press and play really deep rosters than top flight d1 programs, who more often that not these days play pretty shallow rotations. The reason I might try fcp with a D prestige school, I would recruit deep teams of 580 level guys who were suited to fcp, regardless of core skills, and take my chances, since a D prestige school really isn't going to be able to slug it out with the 850-950 level players the top end d1 team play with going man to man.
My son and I were just talking about how high level d1 recruiting is somewhat about bringing in ranked guys - regardless of the fit - and if they fail - you send them packing - while in d2/d3 coaches much more recruit 'their' kind of guy - obviously all d1 coaches try to get their kind of guy too, but few will pass on a highly ranked local guy, regardless of what type of player he is. At d2/d3, there are dozens of kids all pretty much the same, hence, you can be choosier for specific skills, again, sort of like the way the game is right now - for those who are counting, that is two compliments towards the new recruiting system.
One of the reason we have had success in moderately high level aau, is my son has gotten lots of players that are not d1 prospects, but are better basketball players as 15 or 16 year olds ... our best team has a 6'1" 215lb pf, who is 15 years old, started at mlb/fb on a division 1 hs football team, played PG on his hs basketball team, and looks like he is 21, he shuts down these 15 year old 6'8" pinhead type PF kids that our state has coming out of its ears, breaks the press, gets the ball in the high post vs zones and distributes, but lets face it, those 6'8", 175 lb pinheads are going to get d1 offers, our kid won't.
