No. There are some similarities between the 2, but catchers generally develop slower, and Parra was a bit older than Severino is when the O's acquired him. He was also dramatically deteriorating defensively when the O's got him. He had previously been a mediocre hitter known for his good fielding. When a 28/29 year old OFer has a major deterioration in his defense like Parra did, ya gotta figure he's not a player you should go after.
Is Severino going to continue OPSing 1.1? Obviously not. But I think he's developed into a solid starting catcher at 26, and that's more valuable than a 28/29 declining corner OFer.
