Let me just get this out there, I'm going with what most experts think will be their pick, and I can see why.
Arizona has both several needs and play-makers at certain positions.
Fitzgerald, And Breaston At WR
Hightower And Wells At RB
And Just like any team they have their needs. They Desperately need a QB, they have no notable LBs and Joey Porter isn't getting any younger. So why not go with the surpluses of talent at QB this year? Because they NEED better defense. Their Rankings for Defense Are;
Overall Defense In Yards Per Game: 29th out of 32 with 373.6YPG
Sacks: Tied for 18th with 33 Sacks
Then you can go On with how bad their Defense Was in points per game etc. I don't think you can pass on an outstanding Pass Rusher Like Miller. He Reminds NFL's Mike Mayock As A "DeMarcus Ware" Type pass rusher, and is listed as his number 2 player in the draft. Smaller, but a great talent and has amazing athletic ability in both pass rushing and coverage. Anyone could use a great pass rusher as Defense wins championships.

And hey, lets say he's a bust and doesn't work out as your offense is still anemic after trying year two with your guys, you can still get "Lucky" in the next Draft!
