Training can be a challenge, to be sure, but not remotely an insurmountable (or head-beating-against-wall) one.
And then, as a result, you get all these customized players that you built specifically for your team.
For me, that's one of the best parts of the game.
Another amazing thing to me about BB is that every single player that isn't a scrub has been trained up an intentional way by another manager, or collection of managers, from the thousands of teams all across the world over the seasons. Some kid in North Dakota could draft a player, train up his ID, then sell him to a guy in Malaysia, who builds up his Passing, and then sells him to a lady in Germany, who trains him on OD, and then a professor from Iceland picks the player up off the transfer list, and rounds him out with JS, ID, and RB.
Seriously, it would make a cool documentary.
But more to the point, if it is the case that the more and more managers aren't training, then I'm glad, because I always incorporate it into my team and that will give me an edge. If you are wrong, and it is not case, I'm still glad, because then there will be more high quality players on the transfer list to choose from.
