Umm ... read that again July. He only replaced ONE starter .. after the first match ... the rest of his starters all jumped 1 or 2 complete levels. Then many of them jumped another level two days later.
That's most definitely not buying new players.
At least half a dozen players jumped a second level within two days ... 75 skill points, minimum .. can you power train a player an entire level in two days? I don't think so.
So, he had to be using personal training the second time. Therefore it's a pretty logical conclusion that he did so the first time as well. At 4 tokens a skill point, he had to have dumped 2700-3000 tokens into his team.
