He's nothing like Kelce at this point because that's not how he's used. Almost every catch is a couple yards from Allen, uncovered. He had 6 catches for 47 yards last night. YBC is 4.3 yards, YAC is 4.3 yards.
They need to do something else with this kid other than short gain 3 step outs. Time to send him downfield or to roam the middle like Kelce.
