NFL Network’s Ian Rapoport adds that Concepcion’s fully guaranteed rookie contract is worth roughly $20 million. Earlier today, we got word that Concepcion and fellow rookie WR Denzel Boston are already taking full rotations with both the No. 1 and No. 2 offensive groups, which is good news. Browns WR Jerry Jeudy currently occupies the No. 1 spot, but that could change if one of the two rookies pens a strong case this summer.
