You answered the title of this thread. The detailed question that was asked... Let me see if I can find it...
Just bought this guy and think he was good value as a 19y/o but wondered what other people think I am currently training 1 position training at pg or sg and was going to train this guy as well. What do the pros think??
I don't profess to be a pro by any means, but I know that when he has at least 3 better training options, the answer that makes sense to me is "This player is not of good value (to this specific team!) as you have at least 3 better candidates in the 2 positions you would train him in. These 3 players would not only have a better chance of training to a higher level of player, they will also be of greater value should you decide you need a better player in another position. You could train in multiple positions, but as your team is a good well rounded team for your division, you will need an aggressive approach if you wish to catch up to the teams in the next division should you be promoted."
For the record I will once again say that I said he is good value to 90% of lower division teams, but that he was not suited to his teams situation with there already being too many better options. Also I will say that your situation is much different as you started when the game was still rather young and had a lot less margin between you and the higher ranked teams, therefore team training was and still is the best strategy as you can maintain a good, equal roster. But it is an uphill struggle trying that same strategy trying to build a team almost from scratch to try and compete against the teams who have many seasons headstart on you.
I am aware that he doesn't need MVP's and HOF's in his team (note how my main trainee is allstar), but if he has 2 of them and is buying a star in the same position, it is counter productive for his situation. Not only is the star going to cap earlier reducing the quality of player, he will also have less of a resale value reducing the benefit of training over one with more potential. Therfore his team will not benefit by training him over the other 3 options. And as for my training, my player is rated as the starting SG in the U21 national team because he is well rounded. All the skills you listed that go a long way all pop quicker in single position.
And I never once said your player wasn't good. His skills are incredibly well rounded and I commend you for that. What I was saying is that he could have been trained a lot faster than that and my trainee whos skills I listed will have much higher skills at 25 if still being trained in single position. I can see what you are saying about how your strategy works for you, but your strategy is nothing like mine (and the situation being discussed) where you need to get almost instant progression rather than maintain a standard. I am over trying to explain now.
