I think that it has to be AZ and the Over or Pitt and the Under...
The key to looking at this is Arz at 20 points...Pitt at 27 points...assuming a line close to 7 and 47
Your way of looking at it says Pitt D is good enough to hold Arz Off to under 20 points or there is no way Arz D can hold Pitt to Under 27. The first may be true but the second is not as likely.
My way of looking at it says Arz D can hold Pitt to under 27 or there is no way Arz can score 20 on Pitts D...this seems to be the more likely outcome if you ask me...
wouldnt it be az/over and pitt/under? if az wins or keeps it close, you have to assume it's a high scoring affair. if pit wins, it's very possible that they'll still be able to score 27 and keep AZ to under 20.
i agree with SINGLEMALT,its either pitt and under or ariz and over........if ariz is going to win this game then they are going to score a lot and pitt will also score some so thats the only way to really look at it if you think ariz can beat them
