If you read what he suggested, under point 2, you'd have an equal replacement. That means you can't train your injured player and his GS will deteriorate, however you'd have an equivalent player at your disposal.
The equal replacement is complete nonsense of course. Never heard of teams being able to bring in a miracle replacement player. There are deadlines to add players eligible to play certain games. I'd rather have injuries taken out of the game (or just removed during playoff time), before such a whack solution becomes part of the game.
What would be next? A fouling out insurance? If a player fouls out a lucky fan with equal skills joins the game? You still lose out on GS and training minutes though. Wouldn't that be some sweet stuff? Or maybe an insurance against too many minutes? If your game goes into OT random lucky fans with the same TSP finish the game. So many great possibilities.
