We obviously know Riley to be an almost unfailingly pleasant sort. But his anger was evident last August as he discussed true freshman receiver Derrion Grim's decision to transfer. Along those lines, Riley was uncharacteristically short with media in December as he confirmed redshirt freshman receiver Lavan Alston's departure.

Those two players spring immediately to mind as Nebraska coaches mull the best options to fill receiver positions, as does Keyshawn Johnson Jr., a member of the Huskers' class of 2017, who is home in California on a "leave of absence."

With Johnson at home and McQuitty out for the season, Nebraska is down to one receiver from the class of 2017 -- speedster Tyjon Lindsey, who generally has been impressive in camp to this point.

If you're a Nebraska fan, you probably cussed speedster Jamire Calvin for giving the Huskers the runaround in the last recruiting cycle, surprising them with a verbal commitment in late January before ultimately choosing Washington State on national signing day. Flightiness aside, he would come in handy right now.

You could say the same about Dez Fitzpatrick, the receiver who gave Nebraska one of those dubious silent commitments following the Huskers' upset of Michigan State in 2015, only to head to Louisville instead.
