Some folks mentioned that if we keep adding players, guys like Tai won't want to come here. That's simply not true. They can come here, compete against NBA talent for two years, and then have a real shot at a rotation spot like Willis or Hawkins in year 3 and 4. All that said, it would be hard to even have a shot if you have 7 or 8 NBA guys ahead of you. The Alkins/Bolden equation would end up screwing over guys like SKJ and Humphries because Gabriel would have to play a lot of 4 and that would make Bam spend most of his time at the 5.
That said, Cal is going to probably try to add Bolden in the Spring (or take a real shot at him anyway). The lack of a back-to-the-basket physical big is probably driving Cal crazy, and I have my suspicions that although he's added one of the most physical bigs our program will ever witness in Bam, Cal will probably add one more to dominate the paint next season with Bam.
If he adds Alkins and Bolden, however, it would mean UK threw some fellas to the wolves (and I think it's a real long shot as UK hasn't really been mentioned with Alkins lately). The rotation would feature 6 or 7 legit NBA guys in Bolden, Bam, Gabriel, Alkins, Matthews, Monk, and Fox. Is SKJ a year away from doing what Cal wants him to do on a consistent basis (purely conjecture on my part, due to his frame)? If he's ready to go next year, Gabriel would see more minutes on the wing, would he not? Humphries, SKJ, Willis, Tai, Dom, and Mychal would compete for the last rotation spot. That would probably lead to some bad blood as at least three of those guys deserve minutes (Derek, SKJ, and Isaac).
People may not like hearing this, but Cal didn't promise those guys much more than a real shot. They're getting that real shot this season. If they solidify a role on this current 2015-2016 team, the whole narrative might change and Cal might pull back the reins on adding some spring commitments. That said, if Cal doesn't feel confident in any reserve wings besides Matthews for next season, I could see a scenario where he tries to add Simmons, as I see him buying into a secondary role. I'm not sold on Alkins wanting to come here with Gabriel, Monk, Matthews, and Willis deserving minutes on the wing and UK likely to land another big in the spring.
It probably becomes either a wing or a big in the spring, and again, that will likely depend on the development of Tai and Isaac, as well as the progress the staff feels SKJ is making as a senior.
