Graham was one of the worst WRs in the league last year, so I'm not sure why anyone thinks he might be very good, other than hoping it to be that way. Maybe he learned how to catch and hold onto a football in the off-season. Who knows? I do know that looking good in no-contact drills is incredibly meaningless.
I wil feel that the guys they just got are the real deal if Graham doesn't make the opening day roster.
Hopefully, I'm wrong and Graham becomes what some seem to think he already is, but if you can't hold onto the football in college and in your first professional season, color me doubtful.
