Behind freshman starter Adrian Martinez, Nebraska football doesn't have much in terms of quarterback depth.
Andrew Bunch was a walk-on this season, but wound up getting some valuable playing time early in the year when Martinez went down with an injury against Colorado.
The Huskers lost the games in which he played a major part, but Bunch played well enough that he probably felt as if he could compete as a scholarship player, and perhaps for a starting job elsewhere.
Bunch is "exploring" his transfer options, though Nebraska is keeping the door wide open for him to return.
In a recent interview on KLKN, Frost revealed that while he is going to let Bunch pursue other options for continuing his college football career, he will be welcomed back to the team "with open arms" if it doesn't work out.
"I really like the kid, and I want what's best for him. I think after talking to him he just wants to explore his options and see if there's a place out there where he can get out on the field and play or have a better chance to get on the field and play. If he doesn't find that then we'll welcome him back here with open arms. He's been a great teammate and a great part of our team. I want what's best for him no matter what he decides," Frost said.
Per 247Sports, Bunch was a three-star Pro-Style quarterback coming out of the state of Tennessee back in 2016.
In five appearances in 2018, Bunch went 31-for-47 with 320 passing yards, two touchdowns, and two interceptions.
On the ground, Bunch had 16 carries for 40 yards.
Quarterback was not the biggest issue for the Cornhuskers in 2018 though as the defense allowed at least 24 points in each of the first six games for an 0-6 start.
Nebraska finished the season with a 4-8 record.
