Okay, so I can say it a little more nicely that he was "barely productive in his rookie season."
There is zero comparison between these players accomplishments in their rookie years. Quite frankly, given what we have seen from XL so far we would all be very lucky for him to end up as a top 15 WR in franchise history. Cam's talent was very evident, significantly less so for XL. It's obvious that he is an athlete and very much less so that he is a football player.
Don't get me wrong, I am not rooting against him because that doesn't help us at all. The pick is already spent for better or worse.
I am just firmly in the camp that doesn't really think he will pan out. I also think he will firmly be entrenched as the 3rd or 4th option by the end of this upcoming season.
Hope he proves me wrong.
