Can a coach really deem a player who is out for over a month as day to day? Gotta figure the NFL would step in if that was the case.
Eli sounded upbeat - if he was out longer I think he would be a little more down. I predict he misses one game for what its worth

They can say whatever they want about his injury status. As long as they report the truth on the injury report then there's nothing the NFL can do.
Even still.... The Gaints can play a game of cat and mouse all month long. They can say "Eli didn't practice; but he looks ready to go" all week long; then undress him before the game an say "Eli feels stiff and sore and will not play today". Honestly... what can the NFL do. As long as the Gaints report wether or not Eli practices; theres no penalty for this. Nor should there be.

They have to list his practice participation on Wed. amd his status for the game - truthfully - on Sat.
"Did not Practice all week" and then "questionable" for the game and then declared "inactive" would generate a slap from the NFL. What can the NFL do? They can fine the team a hefty sum of money is pretty much their only recourse (plus instructing their officials to call Giants' games very tight, or assigning poor refs to Giants games, or being generally unpleasant)
That is why I asked a while back in this thread whether anyone thought Mort was correct and that the Giants are being hush hush until they must report something.
Is a sprained AC joint as bad as a shoulder separation?
I think the 2nd opinion is wise, and I think it is funny that Manning is seeking it. He'd only be seeking a second opinion if he didn't believe the prognosis from the Giants' docs.
Now, all this said, if Coughlin is playing a B.S. game with his star/franchise QB, we will see him GONE very fast.
