Everything Ive seen points to Butler be a WOLB like Galette. We need a SAM who can cover and rush and Butler isn't exactly known for his coverage abilty.
Of all these I like Jones for a SAM since he has shown he can do all 3 things required of the position.
Werner is overhyped if you watch enough tape you will realize he isn't a high motor guy if he gets blocked initially he tends to give up on the rush and he isn't very good against the run. He was once considered a top 10 lock but as more info has gotten out people have realized he isn't worth a top 10 selection. Questionable motor, inconsistent, disappeared for long stretches.
In Ryan's scheme each outside position has a specific jobs
WILL Setting the edge vs the run( defending the right side "C Gap") and primary pass rusher.
SAM Covering tight ends and backs, defending against the run defending either the left side B or C gap depending on what the LDE does. and is the secondary pass rusher.
Galette and Butler both fit the WILL and not the SAM as neither are what you want dropping into to coverage.
And Tez doesn't have the quick read/reaction skills to be anything more than a sub package player at this point
