The Washington Redskins want a second-round pick in the NFL draft if they are going to trade backup quarterback Kirk Cousins, according to a person familiar with the team’s planning. It’s not clear how active the Redskins’ trade discussions with other teams regarding Cousins are at this point, or what other clubs might be willing to surrender in a trade for him. It also is not known if Redskins officials will remain adamant about wanting to receive a second-round choice for Cousins or if the team ultimately might be willing to part with him for a lesser compensation package. The Redskins lack a first-round pick in this year’s NFL draft, thanks to the 2012 trade with the St. Louis Rams that enabled them to move up in the first-round order to select quarterback Robert Griffin III. The Redskins do have a second-round selection this year. Cousins was a fourth-round choice in 2012 and has spent two seasons as Griffin’s backup. He started the Redskins’ final three games last season after Mike Shanahan, the team’s former coach, ended Griffin’s season early, saying he wanted to avoid the possibility of Griffin being hurt again. Jay Gruden, Shanahan’s replacement, has said that Griffin is the team’s clear-cut starter. Cousins always has said he hopes to have a chance to be an NFL starter for some team at some point. But he also has said he is willing to wait patiently for that chance if necessary and do his best as Griffin’s understudy in the meantime. According to multiple reports, Cousins has not demanded a trade this offseason but has informed the Redskins that he would be open to a deal.
