After a successful signing period in December, Boise State football coaches said they wanted to sign a high school quarterback, another offensive lineman and a tight end.

Mission accomplished.

The Broncos added three new signees Wednesday to the 20 inked during December’s early signing period, hitting those three key positions.

Quarterback Riley Smith and offensive lineman Dallas Holliday were known commitments, but a pleasant surprise was delivered to Bronco fans in the form of tight end Tyneil Hopper, from Roswell, Ga.

Hopper publicly announced his committment and promptly signed Wednesday morning, ending a recruitment that saw him exercise patience after getting some offers from the sport’s heavy hitters a year ago, including Auburn, West Virginia and Alabama.

A 6-foot-3, 225-pounder, Hopper had 350 yards receiving as a senior. He is ranked as 247Sports’ No. 20 tight end in the nation.

“Tyneil Hopper is first and foremost an outstanding young man from a great family,” Roswell coach Matt Kemper said. “He will bring not only a physical blocking style, but an ability to stretch the field to Boise State. His ball skills are second to none. He can make all the catches and creates a tremendous matchup problem for defenses.”
