This time it's reportedly special teams (formerly defensive line) coach Phil Galiano, and offensive graduate assistant Andrew Janocko (who came in with Frank Cignetti and the other Pitt assistants.) This is just after the staff was seemingly finalized, and now Kyle Flood has to find two new coaches and a grad assistant.
Given how close Galiano has been to Schiano professionally, it was frankly a surprise that he did not leave sooner. Maybe the opportunity just materialized. Of course he's qualified to be an assistant DL coach or whatever the role is going to be, but it definitely raises some eyebrows to see Schiano taking so many coaches from Rutgers. Speaking of strange, how peculiar is it that Galiano and Randy Melvin are now on the same staff a year after the former took the latter's job?
Rutgers already has a new DL coach mind you, so finding a special teams and/or defensive backs coach (hypothetically, Robb Smith has flexibility to do either) isn't necessarily a huge problem. The bigger issue is replacing Galiano as a solid recruiter in South Jersey. Dave Brock is from the area, but coordinators do not nearly recruit as much as position coaches do. Speaking of Brock, conceivably he could switch to coaching RBs instead of WRs if needed, but that too is pure speculation.
Pretty much Rutgers needs to find a South Jersey recruiter if it's not going to be Brock. For the other guy, it could be North Jersey, Eastern PA, Miami, there are a lot of conceivable ways to go.
Update: Tom Luicci said Galiano will be assistant ST coach with the Bucs.
