New Player Thoughts and Questions

Hello,
I am very new to these types of games, but I am now wondering what took me so long to try them? They are really cool. I have downloaded all four demos and I will be purchasing soon. Anyway, I had a quick question:
I created depth charts and I noticed that when my team played its first regular season game, many players were used. Now, that makes total sense and I wouldn't want it any other way, but I noticed that the top 2 QB's were used interchangeably. As in, they were shifted in and out series to series and often right in the middle of a drive, which seemed odd. I am not sure what to make of this? Was this my head coach making a personnel decision? Is there a setting somewhere where I can determine how QB's are used?
I did notice some unconventional decisions on 4th down. My team went for it at midfield leading by 7 in the 3rd quarter and again from my own 30 in a tie game in the 4th quarter.
Also, just a small cosmetic thing, but the winning team did not kneel on the ball with 30 seconds left and the defense having no timeouts. Again, no big deal to me, but I offer it up in case that is something that they might want to change.
Thanks for reading
