Ya.....I have on a couple occasions done that but prior to this season there was nobody on my bench I could be confident in playing a big game. If there was nothing but league games on the schedule I would let it go.
Going forward that may be able to change some. I now have a 2nd crop of young fast trainers that have the potential to be great (though bound to have misses). I have to find out what I have in each of them which requires game time.
I lost one of my starting ST's for a few days and I plugged in the new 18 yr old and he carried an 8avg and produced a goal per game over the 6 games so he looks like a good one.
I have two wing players but they both are LM/RM and I play only LW/RW so it will be a bit before I finish training their new positions to really know what I have with them. I need to find playing time for a CB and in the midfield but in both cases the starters are just too effective to take them out. But if they have a short injury then I will be testing out the youth.
I just inserted my new GK, he is by far the most expensive keeper I have seen to this point but who knows how that will play out or even how to evaluate how well it goes.
