SANTA CLARA — Jeff Zgonina is reportedly out as 49ers defensive line coach, creating a vacancy and excitement over potential replacements.
Do the 49ers promote from within and re-assign Chris Kiffin, who joined Kyle Shanahan’s staff last season as their pass-rush specialist and has familiarity with the defensive line?
Or, more fascinating, could the 49ers turn back the clock to, (a), Jim Tomsula, their long-time defensive line coach before his 2015 stint as head coach, or, (b) Bryant Young, one of their all-time great players who’s spent the past two seasons coaching the Atlanta Falcons’ defensive linemen.
