Are you post processing holding the same point and the same coordinates

Yes.

They are the same points, but they throw me different coordinates.
Locally, 2meters is about the separation between self obtained WGS84 positions as derived from TxDot non OPUS control points and those obtained by running the data thru OPUS for the real thing.

Is it a post-process result ?.
It is a difference between OPUS results and stand alone results.

i don't understand what you mean by "stand alone results". Do you mean autonomous positioning? OR perhaps TxDOT data sheets on control monuments?
There are many TxDot GPS stations that have not been confirmed by OPUS and using them can result in what you call autonomous positioning, something I relate to RTK.
For static, I usually say stand alone because there is no actual known control point used to confirm position.
I have a suspicious feeling...
He's got an autonomous position.
I NEVER was able to EXPLAIN to my dad, why this did not work.....

With what he's explaining it really looks like separate static observations processed through GNSS Soulutions, One using using us survey feet and the other international feet, made the same mistake 10 years ago, problem echos as very similar.
