It's misleading to compare the pre-injury Rengifro to the current Rengifro. There is no evidence of him being the same player.
In half a season in 2024, Rengifro had 24 steals, on pace for about 48. His pace post-injury is about 10.
His pre-injury OPS (24-25) has dropped about 200 points (~770 to ~570). This year is even lower.
He was hitting 16-17 HRs. This year he has 0.
In short, there's no compelling evidence of him turning it around meaningfully over Pratt/Williams, and he is a bat-first player who isnt hitting.
