FLORHAM PARK, N.J. -- The Killer Bs -- Breece Hall and Braelon Allen -- weren't formed on April 27, when the New York Jets added Allen to their Hall-led backfield by selecting him in the fourth round of the draft.
They also weren't formed during OTA practices in late spring, when Allen grabbed everyone's attention with his smooth route running and soft hands. He was impressive, sure, but running back is a contact-heavy position. You never truly know about a running back until he gets rocked a few times, and there's no tackling in OTAs.
