He was the 29th rated RT in SF. He graded great as a pass blocker but hit and miss as a run blocker. Remember we got him cheap via trade. Consistent with his later reports in NE and also on the Raiders. A RT needs to be a mean nasty run blocker in a power running scheme. A LT's primary talent is pass blocking. Trent Brown is a better pass blocker than run blocker. I obviously agree he can play RT too but I know Onwenu can as well, and Wynn is unreliable having only played 16 of 48 NFL games. And I agree with you that Von said he was a great pass blocker (again bolstering my argument that he's a beast pass blocker more suited for LT).
Shortly after signing him to a record-setting contract, the Oakland Raiders announced that they would be playing Trent Brown at right tackle, bucking the trend of playing a big-money tackle on the left side.

"As a run-blocker, Brown has been hit or miss from play to play as an NFL right tackle. From 2015-2017 he ranked 11th among qualifying right tackles by earning a positively-graded run-block percentage of 10.5%, but
he also ranked dead last among the same group with a negatively-graded run-block percentage of 19.0%."
