As the Butler Bulldogs, the George Mason Patriots and VCU Rams have shown the college basketball world recently, almost anything is possible in March.
Heading into the 2011-12 season, there are again only a handful of teams most would consider to be legitimate national championship contenders.
North Carolina, Kentucky and Ohio State are worthy of high preseason praise, with exceptional returning talent and highly touted recruits arriving.
Duke, UCONN, Pitt, Kansas, Louisville and other big name schools will get their due as well.
Finding the teams that could surprise (and only COULD, if everything goes right) is a much more difficult task. And by the "teams flying under the radar" in the title, I mean ones that could have a chance at an upset or two come March.
Most are not national title contenders. Most are teams with veteran players who have had at least a modicum of success in the past and might pose a threat to a less experienced group when a season is on the line.
Some are probably just wishful thinking. In May, and sometimes until November, it's all you have.
