I agree that the role is changing. And it's been changing. From the 1st pass catching TEs to now, they are becoming more valuable in the passing game. But most TEs are still asked to block on a significant number of plays. From the looks of the overalls, yeah, blocking should be factored in more.
I'm still stuck on what the overall rating means. I think I remember a dev explaining that they're a quick & easy way for casual gamers to compare players. But I think it hurts as much as it helps. Is Graham a 97 on the Seahawks or 49er? Is he a 97 when his team is up by 7 with 2 minutes remaining?
