Danny Trevathan hit on Davante Adams - what if it were Burfict?

[*ochocincos*]

Davante Adams took a vicious hit right in the chin from Danny Trevathan last night, sending him to the hospital.
There was chatter about whether Trevathan should be fined/suspended as soon as it happened.
For the record, Trevathan was flagged for the hit, but not ejected for targeting.
With the NFL putting a big emphasis on player safety and seeing that Burfict was given a 3-game suspension for a much less severe hit in the preseason, my questions are:

1) Should Danny Trevathan be suspended for that hit?
2) If so, how many games does he deserve?
3) What if Burfict had been the one to hit Davante Adams like that?
