Bigmonkey,
Line movement IMO is only something to be cautious of. . . if you like a side for a particular reason, then you should probably go with it. I have played several games this year where the line has gone in my favor (or against my pick, however you want to think of it) but have often taken a unit or two off the play because of it. Sometimes I just let it ride. It all depends on how I've capped the game and how strong the play was in the first place.
In this scenerio, Vegas set the line at 3.5 and the cappers so far have bet it down to 2. This doesn't scare me in the least bit. . . what will be interesting is how the line moves from here till the tip. I assume the public will be on Arizona given what happened in the first matchup between these two and Arizona's success this year. . . the fact they are the #1 seed and Kansas is the #2. . . etc. etc. etc.
If the line actually moves more in my favor and closer to this game being a pk, then I would have to question my play with others as it wouldn't make sense especially if the public is all over Arizona. If the line moves back up to 3.5 or beyond, then this is what I would expect and playing Arizona would be rather easy IMO. If the line stays the same, I would have to question why an even amount of money is on Kansas given the way I have capped the game, but I will still likely play Arizona anyways.
In the end, its only one factor. I thought the line would be Arizona laying 4 or 5 and the line came out at 3.5 which is what I expected. . . I am surprised the line has been bet down early, but that doesn't mean that I'm wrong and those early "wise guys" (or whatever you want to call them) are correct.
Games that I have felt strongly about this year have for the most part been very successful no matter the line move. This is one of those games, but I still want to see what happens up till tomorrow afternoon sometime before I decide how hard I want to hit Arizona.
