During head coach Mike MacIntyre's tenure in Boulder, the tight end hasn't been much of a factor in the Colorado passing game.
Tight ends have accounted for just 8.1 percent of the catches made by the Buffs in the last three years. By comparison, tight ends had 22 percent of the catches during the two-year Jon Embree era.
The Buffaloes don't have a large group of tight ends this year, but the ones they have are talented and capable of putting up solid numbers.
This group is led by senior Sean Irwin, who has been known more for his blocking ability during this career.
