I think you are asking for thoughts from the wrong people. You should go get the players thoughts.
But I will chime in with my thoughts anyway.
We will see basically the same type of offense. With the exception, and hopefully his improvement. He already said they will use more motion.
The only motion they used, was for 7 plays this year. The Landry Shift.
I think they need more screens, and slants. They use the roll out and throw to the TE coming across the field to the flats or around the hash marks pretty effectively. Then they get away from it.
Which reminds me, the need more crossing patterns as well. Dez was great at those. Which we need another Dez type WR. Higgins would be great to bring in. But he will cost too much.
Also need to go deep more. But a great run game will help with all of that.
Take the bread and butter play KC used for years, and with success. Teams finally started to defend it better, but it is still successful most of the time. Other teams started using it as well.
So you keep a RB or WR hanging back, out toward the sideline. Run players down field or the opposite side. And if a play is not there. Maohomes would simply throw it to the player hanging back. Good for a 1st down and a good 10 yards about every time.
Maybe I should go be the OC.
