Solari not only has brought better fundamentals, technique, and being assignment correct to the table, but in combination with Schotty they do far more variety wise in the run game. Making it harder for opposing teams to prepare for. Cable was cool with inside zone, wide zone, zone read, and callled it a day. They are doing far more in the running game now which is critical when you want to be a run first team. It is a hybrid blend between what Seattle has always done, with what Solari brings technique wise, mixed with what Schotty did with the Jets. They come at you in a multitude of ways, and Russ is erasing 1 defensive player nearly every run snap as he is a threat to keep, and teams have to account for that. They play with brains and brawn.
Schotty in the redzone has been phenomenal. A stark contrast to the previous 6 seasons where I feel the team consistently underachieved. Middle fingers are now no longer necessary. I can only recall one actual bad wtf redzone play call. Game 1 vs Denver. 1st and Goal from the 5, and they call a toss sweep with Penny (Instead of running it straight ahead with Davis or Carson.) Schotty fixed this immediately and hasn't done it since in the redzone. That is is really. Schotty also will continue to hammer plays that are working throughout out the game instead of going away from them which the previous guy was notorious for.
Just a small nitpick would be to find a way to get some short quick passes, and running back screens blended into what they are already doing. Plus some RPOs coming off of the mesh of the zone read.
