Let's unpack that statement a bit.
The no blocking rhetoric is often overblown. Is he a great blocker in a power running scheme? Definitely not, but that's true of most pass catching TEs, and it also isn't what his role is anyway. He has no issues chipping on his way into his route in 11 personnel, or holding up a backside rusher on plays going the other way, such as RPO concepts. In 12, it doesnt matter because it's only 12 personnel as a technicality anyway, it's more like a spread fomation. There's no reason for him to be on the field in and short situations. Tell me how his less than stellar blocking skills is really all that detrimental.
RAC? Most TEs don't have a much in the way of RAC yds, when they play against a lot of zone, and our flankers, as a group, don't force man or press. Not sure what you expect when he is asked to sit down in the "soft spots" on a regular basis.
I'll give you not breaking a lot of tackles.
