Pretty sure he was using hyperbole to highlight his point. I think he was looking for a response to the spirit of his comment, not the literal statement. I mean, for the point he's trying to make, does it really matter if a team is $13,249,623 under the cap vs $20,000,000 under the cap? Either way there is room to sign players.
Mind you, I'm not necessarily agreeing, I don't think money should be spent just to spend money, but rather than take the conversation onto a weird tangent of specific dollar amounts, perhaps we could focus on the idea brought up in the discussion?
My response is that the team generally likes to sign their own players and so keeps room in reserve to sign guys during the season. However, if certain needs on the team remain year after year after year after year, then perhaps spending some money on higher level free agents might make sense (mainly looking at OLB and dline here).
