@jfriske:
The major flaw in your NT plan is the dearth of players capable of making the NT. You NEED to have at least superstar potential, and that may be low now a days. If you are training for a well-rounded player, you will also need to make sure they don't have too many holes in those side skills. You'll never make the NT with your well rounded PF if you train him for 4 seasons to get to proficient OD and sensational JS. There simply aren't a lot of players capable of becoming an all-arounder.
You are basically making all the guys like Chuck Rainey useless. Great starting skills, but not enough potential to make the NT.
I think that's a great point and something to consider: if the goal is to develop NT players, what do we do about well trained all-star potential players, or players with gaping holes in their skillset?
For big men, which is where I think a lot of the U21/manager best interest conflicts occur and also where this strategy would be most different from what we're doing currently, I don't think it's that big of an issue because you more or less need superstar or better potential anyways if you're going for mono-skilled monsters, so we wouldn't really be making things more restrictive on them. On the contrary maybe, really balanced/unique perennial-allstar PF's might be able to make the NT whereas mono-skilled perennial-allstars probably can't.
If you know your players has holes that preclude him from making the team, you're also under no obligation to attempt training him as such. Big men will holes would have to do the best they can with the 1-2 seasons of guard-training they have time for, and you're right that some players won't ultimately have the right skills, but at least these guys are trained in a way that is more sustainable for their managers. An affordable, mostly balanced player with a few holes is still probably preferable to a salary behemoth, even if neither can make the NT.
For guards it's a tougher question, but if I had to pick 3 out of 4 guards, all well trained, but one had potential that would clearly exclude him from the NT, I would take the three with the better potential. I think that something past managers would have done too, assuming GS and things are equal. If it's a situation where it's:
13/11 JS/JR
14/12 OD/Ha
12/12 Dr/Pa
9/7 IS/ID
superstar or better potential
vs
15/11 JS/JR
16/12 OD/Ha
12/12 Dr/Pa
4/6 IS/ID
all-star potential
I think I still choose the 1st player with better potential. I think you can make a (weak) case that in some instances the 1st player can be equal or better in game, but even if you can't, I still fall on the side of saying that the 1st player is more likely to add value to the US talent pool overall by virtue of his possibly being NT material someday. If it came down to a tough decision like that between them, I would choose to recognize and reward the hard work of building a foundation for a unique NT player. It's no fault of the 2nd player's manager and I recognize that, but the team can only carry so many players.
If they have grossly different talent levels it's obviously a different situation. Frankly though if we have so many quality trainees that we have to make those decisions, that's at least a good problem to have. If there were not a bunch of amazingly trained high potential players clamoring for spots on the team to the point where we have tough decisions to make, then I'd have no problem finding a spot for an amazingly trained traditional, lower potential player. I'm just laying out my thought process for if push comes to shove.
So in conclusion: there probably is a spot for guys like Chuck Rainey any given year, unless we get an amazing crop of trainees.
