He needs to impose a 10 yr term limit or lower for priests in the Dallas Diocese in a given parish. My home town of Greenville has had a priest for over 10 yrs who has driven almost all of the local families with kids to go to Commerce rather than have them sit for hours at a time in the pews with a parent while taking their CCD instruction straight from the priest on Saturday mornings while their non Catholic friends are playing sports like football or basketball at the YMCA leagues or city leagues. After going through the rotation of the scriptures 3 times, it's a good thing to bring in a new priest with a different perspective of the scriptures in the homilies.

Also, it would help if the new bishop can learn enough Spanish to hear confessions in that language at the Cathedral if he cannot do so already.
