Brandon Moore will still be here next year, and he's a big guy. Ricardo Miller is already 235 or so, and another off season should see him over 240. I don't see burning Williams's redshirt to be a blocking TE only, especially when we have walk-ons near as big as Williams with a lot more college coaching. I don't want to see walk-on TEs catching passes, but if it's for blocking purposes only, those guys can probably handle that just fine.
Hoke was top notch at this aspect of his job.
