True but also, those same players lost in the first round for two of the squads that returned everyone (Auburn and UF) last year.
Auburn basically has all fifth year players (Broome, Mazara, Jones, Cardwell, Johnson) one senior (Kelley) and one sensational freshman. Five of the seniors started somewhere else and transferred in to Auburn. Broome (3/5), Mazara (2/5), Kelley (1/4), Jones (2/5), Johnson (2/5). Only Cardwell and Pettiford have been at Auburn since their freshman years of their main contributors.
UF has Clayton (2/4), Richard (3/4), Chineylu. (1/2), Martin (1/5), Handlogten (2/3) and Alexis (1/3) as transfers. Condon (2/2), Haugh (2/2), and Aberdeen (3/3) are the only major rotational players that have been at UF since their freshman years.
Of the two teams that had very good years last year. Duke has the best high school players to pick from and brought in some great fifth year role players. Houston though is interesting.
Duke has five freshmen, 1 sophomore, 1 junior who are solely at Duke. James (1/5), Gillis (1/5) and Brown (1/3).
Houston has Cryer (2/5), Uzan (1/3), Wilson 2/5 as transfers but probably actually as the most long term continuity with Roberts (5/5), Arceneaux (3/3), Tugler 2/2, Francis 4/4.
I'd say these teams did a good job of bringing in non-fifth year (one and done) transfers and letting the team grow with them (Duke aside who has at least 5 of it's top players as one offs at Duke). Duke aside, only one freshman plays a prominent role for the remaining three teams (Pettiford).
