I think the problem with the schemes has been the pass rush, I don't see how Shelton helps with that.
Hand healthy and Nick Williams helps the pass rush. Add one more de in draft. Okwara needs to play like 2018. Flowers fully healthy instead of slow start..collins at jack..austin bryant healthy, blitz.davis more from jack. Lots of things can help the pass rush
And i think shelton is a little better than harrison and robinson at rushing the passer
