Well...no that's not true. It works entirely based on the on-disc ratings.
Well, he definitely said it several times, I was assuming it was true
If you do, or do not, download teams from the Academy, your gameplay experience will be *exactly* the same for your player.
If you download from the Academy, the players around you will be replaced in name and appearance only based on their order in the roster not their initials. This will seem odd to see what you know as a spin bowler become pace etc.. however you cannot play as them in career mode anyway - your experience is no different.
But maybe things have changed since then.
Or maybe I've misunderstood. People have been mentioning the fact lower-order batsman are getting lots of runs while high-order batsman have been getting out cheaply and bowling since the start, so I assumed that was the same thing as the linking bug.
