From an on-court, basketball standpoint, there's probably nothing to worry about regarding our 2015-16 team in light of these recruiting misses.
If Purvis, Hamilton, and Brimah return, we'll be bringing back almost everyone, replacing Boat with Adams, and adding Enoch. That's a pretty formidable roster, and you could argue we wouldn't even have room for guys like Briscoe/Newman or Clarke/Mack/Jones or Stone who are looking for 25-30 mpg.
If Purvis leaves (unlikely), we'll still be in good hands at the 1/2 with Adams/Cassell/Samuel. Getting Newman would be a boon, but it isn't necessary.
If Brimah leaves (unlikely), we'll be in big trouble at the 5. Under the small chance this does happen, losing Stone would hurt big time.
If Hamilton leaves (possible), we'll be in trouble at the 3. If this happens, failing to get a top wing will hurt, but this is maybe a 50/50 proposition.
It's understandably difficult to sell these recruits, who are looking to start and get major minutes right away -- as they should -- on being an insurance policy.
Unfortunately, this issue clouds our ability to say whether the staff is truly underperforming on the recruiting trail. In a vacuum, we should be doing better, but these playing-time concerns could be the major factor. Only in subsequent years, in which we're offering guys basically open spots on the roster, will we be able to determine whether our coaches, brand, prestige, and reputation are sufficient to win these high-profile recruiting battles.*
* Adams and Enoch were important gets, but we basically didn't have to beat anyone out for them. That's good, but that won't always be the case. Sometimes we're going to have to beat the UNLVs, Wisconsins, UVCUs, Kentuckys, and Tennessees of the world to get the guys we want.
