O'Hara may make a little more sense than Kreutz at this point because DeGuglielmo probably brought much of the Giants' blocking scheme to Miami and so O'Hara comes in knowing a lot of things.
They're saying on the other site that O'Hara left the building without signing, but it has no significance because he didn't want to make the decision without speaking about it to the wife and family and didn't want to do it on the phone.
That is also said on this site. I know because I posted it. One of the media dudes, I think Volin, tweeted that, so I copied and pasted it here. No other forum gets anything up on thephins.com
