Let's not be too hard on Tyler just yet Loyal. The dude is a rookie and SF has a very good defense. Before we lay new nicknames on the guy let's allow him to settle in a bit. I will also go back to some previous conversations we have had here about rookie TEs. It might be the toughest position for rookies to have impact in. Even Gronk wasn't beast mode right out the gate. Cue up Seattle and it's gonna be the same drill, it's a very tough defense on pass catchers.
All I want to see from him is get the experience of being in the games, and help convert a first down or two per game while he's settling in. Same deal as with Coop and Spruce, just a handful of catches between them. If those things start happening this offense will grow a lot.
IMO he will have a game here and there where his talent shows. But I'm just not expecting it to be every week, at least for now.
