Yes, Brown is solid at both LT and RT.
Somehow, Wynn is LAZY because he isn't a solid RT, even though he was OK at LT.
Please note that Wynn's grade at LT in 2020 and 2021 are better than Brown. Even at LT, arguably there hasn't been much of an improvement.
BOTTOM LINE
The stats you point out do NOT show that Wynn is LAZY. They show that he is much better at LT.
As far as stats, the switch of Wynn to RT has been a failure. Switch them back and get on with it!
AS AN ASIDE
I suspect that Brown was moved to LT because he was expected to play be better with a rookie LG.
