Since the Rams supposedly did some exploring with Gilmore and now they are talking to Matthieu, I'm going to guess Gilmore wants the moon. The Patriots didn't give him the huge contract and now the Panthers don't want to either. He's missed some games in recent years. He's still a great man corner but its tough sledding to demand big money with a recent injury history.
Matthieu can play corner. He's been lauded for having a very high football IQ. Its likely Snead and McVay want to duplicate the Eric Waddle effect with one or the other.
They could currently be trying to pit one agent against the other to see if one comes down in price. Either player would provide another veteran presence in a young DB group. I'm all for the Rams signing either one.
