I ran a lot of screens last year FMT, not this year, there's a risk in running them. Man coverage works, and you can't audible your WRs or HB to run a different/quicker route as check down. It's funny because I usually sniff screens out but I don't jump it, reaction is too slow, there has to be a tell because some guys are great at it. I'm content with spilling it inside. HB screens are going weakside 95% of the time, away from some trips formation or away from TE.
With regards to toss, I'm running tosses, your not doing yourself favors by just run inside zone, dive, or stretch, need to keep D off balance. I haven't run much power, but I do run some counters, counters can work really good if the backside numbers are in your favor, no S in box.
