First of all, no. There isn’t a metric where you could quantify him as the best. He was a good piece on a great defense. I would say Freyler, Johnson, Tampa and McDonald all were better this year. Secondly, that literally means nothing to the NFL. It’s all about fit. What position does he translate to in the NFL? Not an EDGE and maybe too small to be a DT. He would be a solid 3-4 end but teams are trending back to 4-3 it seems.
Like I said, good luck to him, but why leave early if you aren’t a for sure day one or 2 guy?
