There are no diplomas awarded for pass-catching but consider Amani Toomer as having majored in Wide Receiver.
He spent his entire 13-year NFL career with the Giants and owns the franchise reception record with 668. Odell Beckham Jr., in only his fifth season, has 390 and is rocketing up the charts, currently No. 4 on the list, behind Toomer and running backs Tiki Barber (586) and Joe Morrison (395).
There is no way to hold Beckham back from scaling the heights. And Toomer knows it. He knows how good Beckham is. He also sees Beckham as an unfinished product capable of much more.
