My previous sliders - I had human pass blocking at '0.' Seemed to work out well, at least for me. Human Catching was also at '0' and I still had a high completion percentage.
Again, I use a ''player lock'' style where I only control the Quarterback. I do not, at any time, switch to any other player. Which means, when I hand the ball off, I let the RB go. When I pass the ball, the WR does what he does. I also ask Corso on offense, no matter how stupid the call is. So, we're not going to get the same results.
I just find the game to be too easy, on every level, if I control every player. I'm actually finding the game to be a hell of a lot of fun, and competitive playing this way, so I'm hooked.
