since this thread has been necro'd just a little bit, i'll ask a few more questions. Keep in mind i'm a guy that really masters the art of the TL, i know next to nothing about the training regimens other than how to get 3 trainees into 1 position training and 6 into 2.
1) Lets assume that at most the world-renowned trainer gets no more than 3.5-4% better in the best case scenario. Why would even a NT need someone that good to train up NT team players? For that little a gap, i'd think a level 6 trainer is the highest anyone would ever need to go to get someone worthy.
2) Just briefly i've looked at some D.I teams across a few countries, and the highest salary i'm really seeing is 250k on a HOF, and 150k on a superstar. Thats on the low end of both caps, and none of them are capped. The fluxuations between the top and bottom seem reliant on training certain salary-hogging skills more than a potential trainer level change. This still holds true across national teams. So i have serious doubts that a NT is going to be make-or-break on the perhaps 2 or 3 pops he might get with a top end trainer. Am i flawed in this thinking?
