1. SGs do have a place in LI, but not in the manor I'm describing them. SGs is the least valuable position in BB. Does it have value? Absolutely. But would I play Yi, or a Yi type SG in a LI tactic? No because his lack of passing will harm the offense more than his great shooting will help it. Now, with that said I'm going to clear up my stance of SGs. Do I want our top guard prospects, ones that have a legitimate chance of the NT, to be built into SGs? No. I'm only going to recommend a manager turn his 18 into a SG if the prospect is around 6/7/7/4/4/4. and skills of the nature. That player is not going to be a U21 candidate if they take the time to train the passing up to a respectable level. And by that time a good season of prime training time has vanished. That player will be on the U21 radar though if they pump JS/JR/OD with some secondary 1v1 weeks. That prospect by age 21 will be 15/14/14/10/10/5, and a damn good player.
As for the 2nd part of your question, I'm not necessarily looking to move away from LI, but at the same time I am not content with telling people to train their players as if we'll be running LI. That eliminates options, and I like choosing from options. It allows me to choose the best team, instead of hoping this LI team that is waiting for me is good enough to win.
Also it is a known BB fact that 3p% is drastically decreased when running a LI offense, so playing a true SG, no matter how good, in LI is a waste of their talents, and harmful to the team. Put Irizarri in a RnG, or Princeton, and he's probably our highest scorer.
I'm great at building teams. I like SGs, and PFs, but if we have none that are talented, I'm not going to be biased and pick them if they don't fit in the team plan.
2. Hamel is my ideal PF. He was 11/6/5/8/8/5 15/14/7. You could nitpick with the 7 rebounding, but you'd be wrong. He was a stud. You take that build and run, no matter your ideal build.
3. At this point, I'm not going to interfere much with the season 27 guys, because the player is 20 y/o now, and following a predetermined training plan, so I'm not going to come in and tell them that what they've been doing is wrong, and to now follow my plan. If they've been told to go with a LI PG, I can really tell them to cancel that and go with scoring PG. If I see a prospect that I feel can go another route, I will contact the manager, find out what they're doing, and if it's different than the view I share, I'll see how they feel about my plan. If they decline, there is not much more that I can do.
Just glancing at the current age 20 crop, I can already see we're going to be an inside oriented team. Devin Farnworth may go down as the best PF the U21 has ever seen, Bob Chavarria is an incredibly advanced PG with great ID, and the next seven highest players, sorted by TSP, are all guards with great inside secondaries. That team has an identity, and it's an inside oriented one. It would be moronic if I tried and changed it now.
