I mean, hard to debate with “arguably best defensive lineman.” You could argue Oliver was better but not more productive.
Phillips was #1 in sacks, 2nd in QB hits, tied for first in TFL, and #1 in solo tackles on our DL last year. I was encouraged by Oliver’s play last year, but JP stuffed the stat sheet last year. There’s a reason he went from a prove it deal to $10M AAV.
