I think Staal is trolling and will play game 1.
With the lack of comments, I'd guess Clowe probably has a lower body injury + concussion, so who knows if he comes back at all.
A lot of people don't like it, but times like these you want the nfl rules that require them to tell the media everything. Stops arguments over mystery injuries and return time tables.
The fact that he didn't rule it out makes me think that it's a serious possibility. It's a very NYR thing to tell us nothing, and then we turn on the TV Thursday night and he's out on the ice. He sounded positive in his comments earlier today(posted on this thread), so I think that if he thinks he can do it, he'll play.
My guesses for order of return
1-Staal(Early in round 1, maybe thursday?)
2-Dorsett(Sometime next week probably, although Thursday isn't out of the question)_
3-Clowe(If it's a concussion, late 2nd round seems likely (4 weeks ish), if it's not, who knows)
4-Boyle(We know nothing about him, and based on that I can't imagine it's good)
It's totally possible that Clowe just pulled something and was taking a rest day, but that looked quite a bit like a concussion to me. Staal/Dorsett should be fairly soon, with Boyle being the wild card.
