The second one (against the Steelers) has to be one of the single best catches I've seen in recent memory. Not only is he tight roping the sideline, somehow managing to get both feet in bounds, but he's doing it with a cornerback draped all over him and Minkah Fitzpatrick, one of the best safeties in the NFL, bearing down on him, trying to knock hm out of bounds.
That's not a play I've seen many receivers make. Yes, there's the one-handed catches, the diving catches, the usual toe-taps, but this one is something I don't see every day, and based on the sheer difficulty, especially from a rookie, I have to say that's my favorite.
