The rash of first-round signings is expected to continue on Monday.
Per a source with knowledge of the situation, the Browns and running back Trent Richardson are “very close” on a new deal.
Richardson, the third overall pick in the draft, would join Lions tackle Riley Reiff (No. 23 overall), Steelers guard David DeCastro (No. 24 overall), and Cowboys cornerback Morris Claiborne (No. 6 overall) as players agreeing to terms on Monday.
It also would leave six first-round picks unsigned, including the man who likely will be handing the ball off to Richardson, Browns quarterback Brandon Weeden (No. 22 overall).
