The Detroit Lions made a change to their roster on Monday by releasing wide receiver Brian Robiskie. The move wasn't made to clear a roster spot for someone or anything like that. Instead, the Lions simply decided it was time to let Robiskie go.
Robiskie joined the Lions in the middle of the 2012 season and ended up playing in six games. He became an injury replacement, and he recorded 4 receptions for 44 yards and 1 touchdown in those six games.
While this does seem like a rather random move, it's not like Robiskie was necessarily expected to make the team this year. He was facing an uphill battle with so many other wide receivers on the roster. Things are wide open at wide receiver after the top three of Calvin Johnson, Nate Burleson and Ryan Broyles, but Robiskie would have needed an outstanding training camp to actually make the 53-man roster.
Robiskie especially would have had a tough time making the team if the Lions go out and draft a wide receiver. That would seemingly solidify their receiving corps, and even if they don't draft one, the receiving corps won't include Robiskie going forward.
