He's ridiculously slow, so we can never expect a lot of yards after the catch with Spaeth, but he can certainly use his big body and long arms to present a nice target in the red zone and at the chains.
As long as he catches what's thrown his way I'm fine with no YAC,we have other WRs that will provide the YAC. Spaeth's biggest role will be a chain mover and TD maker and there isn't anything wrong with that.
By the way, your sig is the absolute best so far. I wish I had thought of it.
