A blocking wide receiver who can catch

Um no. I’ve literally never heard anyone say that about a wide receiver. A tight end, of course, but not a receiver.
Here's the first reference I found in 5 seconds. It's from 2004.

Early in the playoff game on Christmas Eve 1967 against Cleveland, Bobby Hayes had run a long post route. I went in to give him a few plays to catch his breath. Meredith decided to run Walt Garrison to the weak side, where I had replaced Hayes because I was a good blocking wide receiver. I broke my leg and dislocated my ankle when Walt shook Browns safety Ernie Kellerman off into me.
Eric Martin was often referred to as a good blocking and possession wide receiver. There have been many other receivers referred to as "blocking wide receiver" going back for decades.
