The Redskins placed a claim on tackle Desmond Harrison, according to Field Yates of ESPN.com (on Twitter). Ultimately, Harrison went to the Cardinals, who had top priority when the Browns cut him loose. 
It’s potentially a sign that the Redskins are concerned about Trent Williams‘ holdout and also an indication that they are eager to bolster their offensive line depth. For example, the Redskins want to use former Giants first round pick Ereck Flowers at left guard, but he has been practicing mostly at tackle due to Williams’ absence and a lack of other available options.
Harrison started in the first eight games of the season for the Browns before losing his gig to Greg Robinson, so it was widely expected that several teams would try and grab the 25-year-old. It’s possible that other clubs were warded off by Harrison’s reported absence and tardiness to team functions this offseason, but there could have also been issues with his game tape. Despite being a first-stringer in the first half of the 2018 campaign, Harrison graded out as just the No. 67 ranked tackle in the NFL last year, per Pro Football Focus.
Looks like he’s got a squid on his head.
