According to pro-football-reference.com, he had 5 drops last season. He didn't catch all of his targets, but the hit in the hands constantly might be an overstatement. He had 54 catches for 848 yards on 92 targets. That is more catches and yards than every Saints receiver last year and he had less drops than AK did, who had 9.
Cardinals vs. Seahawks Week 18. Watch the entire game and get back to me about those 5 drops. There’s a reason the Cards weren’t overly interested in retaining him.
