One thing to keep in mind, though (and this was discussed when Heupel was hired), Heupel likes a variety of WRs in his offense. So if he’s got a big strong WR on one side, a jitterbug/quick guy in the slot, and a tall, fast, lanky, body control guy on the other side, he’s got his variety. That pretty much describes Smith, Matthews, and Brazzell.
Another thought would be to have Smith and Matthews on the outside and Brazzell in the slot. That takes Brazzell off the LOS and makes him less susceptible to physical press coverage. If lack of physicality is the concern with him, that is. Worked with Hyatt.
