This past week of college basketball was highlighted by a plethora of upsets – especially over the weekend when we saw six top 10 teams fall victim to the upset bug. Starting at the top, previously unbeaten and top-ranked Arizona suffered its first setback of the season Saturday evening when it was bested on the road by California. Previously 4th-ranked Kansas was also a road victim earlier in the day, as the Jayhawks were thoroughly outmanned in a defeat at the hands of Texas. Previously 6th-ranked Michigan State, a team that is suffering through well-documented injury issues, started its week off with a bang by winning in overtime at Iowa. But that victory proved to be the Spartans’ only positive tally of the week, as they fell to unranked Georgetown on Saturday in a non-conference game played at Madison Square Garden. Previously 7th-ranked Michigan entered Sunday’s game at Indiana as one of the hottest teams in America — the Wolverines had won 10 consecutive games and sat atop the Big Ten standings with an 8-0 record. None of that mattered in Bloomington though, as John Beilein’s team struggled offensively throughout a 63-52 defeat. Previously 9th-ranked Oklahoma State suffered what was probably the most puzzling loss of the week, as the Cowboys were bested at home on Saturday by a Baylor team that had lost six of its last seven games prior to Saturday. With February now in full swing, there is really not much that can be considered unexpected – especially with how this season has played out thus far – so you should expect even more shocking upsets moving forward as teams jockey for March position. The quick n’ dirty analysis of this week’s poll is after the jump.
