Not questioning the coaches as the see day in and day out the player performance in practice. That said, Broc Thompson should get more touches.
Others that I'd like to see & know if they are close are: Preston Terrell, Abdur-Rahmaan Yaseen, Kory Taylor, TE's Kyle Bilodeau and Paul Piferi. The last two plug in as possession WR's if needed since we use WR's in short passing routes as runs, then get the ball to a bigger body that may have enough speed to take contact and get yards after catch. A WR at ~ 250 lbs would be harder to get to the ground than a 190-210 lb guy. Why waste speed of Piferi who reportedly ran in California track in the speed events.
I guarantee that IL would not have game planned for that.
I remember the days of Kyle Ingraham at 6'9" TE towered over others and did well in red zone. The only thing that kept him out of the end zone was grades if I recall correctly. Dang that hurt to lose him. I know this...6'5" some wheels and a good frame = 3rd down possession or goal line corner jump balls.
