Steelers TE Heath Miller answered questions for steelers.com:
How do you think you will know when your knee is ready?
"I’m not sure. I’m sure it will be a collective decision made by a lot of people. Like I said, I try not to think about the big picture too much and just approach every day and try to get better."
What are you able to do now that you weren’t able to do during mini-camp?
"I’m pretty much doing the same. I’m just trying to get better at what I was doing. Really, mini-camp was only a few weeks ago so it wasn’t that long ago. Just get better and better and feel more comfortable with what I’m doing."
It sounds like rehab is going well for Miller, however there isn't a timetable for his return. We rank him 27th but admit there is potential for him to rack up targets assuming he's healthy and especially with the loss of WR Mike Wallace. Miller's ADP indicates he's going undrafted, and there are much better things to draft late-round than a second TE, but there is some potential for Miller.
