They are Super Bowl volume re-routes. Normally, those flights you listed would file their arrival route as IIU DECEE4 arrival. However, for Super Bowl volume ATC requested south departures and no SID filings and for pilots and dispatchers to file IIU as their initial departure fix. In order to prevent arrival flow and departure flow from conflicting, ATC issued tactical re-routes both published and unpublished for flight thats normally file the arrivals such as IIU DECEE4 to transitions on other arrivals such as PXV RACYR1 and ROD CLANG5.
ATC does this all the time at major hub airports. ATC calls it offloading during normal ops. When one fix becomes constrained, ATC simply sends traffic to other less constrained fixes. In the summer, I had a CLT-JFK flight I filed MERIL4 MERIL RDU J209 ORF J121 SIE CAMRN4. There was a little bit of weather and a lot of JFK volume but no published CDR or playbook re-route but my guys were all given ZAVER2 VXV J43 ROD J29 DORET J584 LVZ LENDY5 by ATC on clearance. A very significant change for the CRJ200 in burn and fuel requirements especially when you have no advanced notice of such a major re-route.
