I don't know about AB or how the WR rotation will shake out, but I think you'll see a lot of different TEs this year, and some of them will probably line up in the slot at times. Zamora, Ward, Hill, Hjelseth and Jacobsen, at a minimum, will see time. And you'll see guys like Bryant and Zamora line up at FB and then motion out into the formation. Hill has looked really good in pre-season and Jacobsen was very effective in spring ball before getting hurt. Hopefully he'll be back on the field soon.
PS--Luke Austin and John Davidson each have 5 total catches in the two scrimmages, that would lead me to believe they might see some time. I'd say it'll be Burel, Moore, Krosch and Rumble getting the majority of the reps.
