Quick look at the tight ends for the season:
Tanner Hudson: 8 receptions on 11 targets (73%) for 93 yards (11.6 per catch), 5 first downs (45% of targets), and 0 TDs. --> 3 games played
Irv Smith: 13 receptions on 19 targets (68%) for 83 yards (6.4 per catch), 4 first downs (21% of targets), 1 TD, and one fumble lost. --> 8 games played
Drew Sample: 6 receptions on 8 targets (75%) for 40 yards (6.7 per catch), 1 first down (13% of targets), and 1 TD --> 8 games played
Mitchell Wilcox: 3 receptions on 4 targets (75%) for 17 yards (5.7 per catch), 0 first downs, and 0 TDs --> 8 games played
The sample sizes are small, but it seems pretty clear to me who should be getting the majority of the opportunities in the passing game.
