I guess I'll trot this out for the 1,001st time. The difference between DA and every other developing receiver who's ever been compared to him in GB since then, is that DA showed all that he was capable of in his rookie year. He was the best WR on the field in the playoff game vs. DAL (with peak whatshisname that didn't catch that ball) in the second half. He was open a lot more than he got the ball too but AR went other places with it. Getting separation off the line, breaking ankles on moves, YAC, toughness through the catch and tackle. He was doing this his rookie year in the divisional round of the playoffs.
He needed to get more consistent with that production, and the ankle killed year #2 of that process. But there was no wondering what he was capable of after that game and the regular season win vs. NE. No young receiver in GB has shown that ability since then and if you see it again, it will answer a lot of questions.
