Is it nuts giving Carson/Juju/Brissett for Watson/Shady/Montgomery?

Carson and Juju were my 2nd and 3rd round picks but man, Carsons fumbling and Roethlisberger’s injury (Juju) have me very worried.

Getting Deshaun Watson fixes a big problem for me at QB and I see Montgomery having some real upside ROS (similar to Carson). Shady is part of the most prolific offense in the league. Even with just 10-15 touches, the upside is there in KC.

This is a standard league and this is how I am rationalizing it. Would appreciate some thoughts.
