IMO - Take Michigan off your list, OVER RATED! The 7/1 is ridiculous and this is NOT last year. They won't even reach the final 8 IMO. I think NC could always get hot, BUT, the look in Roy Williams' eye at times is OMG how can we be this bad when at times we are this good. The incocistancy of their game doesn't fit whats needed for a 6 game run but they are very good when they are on.
That said, looking for value I like: NC 19-1, Nevada 20-1, Marquette 48-1, Iowa State 90-1, and Maryland 140-1 would be may increasing level of teams worth $100 investment for a chance to win between $1,900 and $14,000 among this group.
Probably Marquette and Iowa State worth a legitimate $100 or $200 future each; in fact, I just played them both thanks for reminding me.
