NCAA Tournament 2013 Bracket: Upsets to Watch for on Day 4

The field of 64 has been broken, as the 2013 NCAA Tournament has officially begun. Favorites have advanced and upsets have transpired, leaving many brackets wondering what's going to happen next.

Fortunately for those curious minds, there are upsets to watch for on Day 4.

Many are looking for the first powerhouse to fall, but the bracket has yet to permit that to happen. With that being said, there are sleeper favorites that have emerged as trendy picks to make the Sweet Sixteen.

Some of those teams could see their run end before it gets started.

Some teams are in store for opponents that should have been seeded higher than they were. Others have been caught in a matchup in which their statistical weaknesses are matched by teams who thrive in said areas.

So which teams are on upset alert for Day 4 of the NCAA Tournament?

No. 5 Wisconsin versus No. 12 Ole Miss, West Region

This has become one of the most popular upset picks, as Marshall Henderson leads SEC Tournament champion Ole Miss up against the Wisconsin Badgers. Although Wisconsin has been underestimated, this is an upset to watch for.

Marshall Henderson is hardly the only reason why.

Ole Miss is an offensive power, registering 78.2 points per game. That's good for seventh in the nation, in spite of the Rebels' 43.7 percent shooting from the floor.

What helps is the fact that the Rebels have five players averaging at least 8.0 points per contest. What hurts is that Henderson, Ole Miss' leading scorer, is shooting 38.5 percent from the field.

Fortunately for the Rebels, when Henderson is on, he's one of the best players in the nation. That's a major reason this is an upset to watch for.

Which Henderson will we see?

No. 8 North Carolina State versus No. 9 Temple, East Region

A No. 8 versus No. 9 battle is hardly grounds for an upset. With that being said, North Carolina State was the No. 6 team in the nation entering the 2012-13 season.

They have the raw ability to upset Indiana in the second round and make a run to the Final Four. They also have the lack of chemistry to go out in the Round of 64.

Temple's Khalif Wyatt is the perfect player to send them packing.

Wyatt enters this game averaging 19.8 points, 4.1 assists, 2.9 rebounds and 1.7 steals per game. He scored 33 points in an upset of Syracuse, 26 in a seven-point loss to Kansas and 30 in a win over VCU.

In other words, he's a primetime performer.

N.C. State holds the talent edge, but their chemistry has been questionable since the opening week of the season. If they've still yet to put it all together, Wyatt and the Owls will sink them.

This is as unpredictable a game as you'll find.

No. 7 Illinois versus No. 10 Colorado, East Region

The Illinois Fighting Illini are gaining steam as Cinderella favorites due to the presence of clutch scoring guard Brandon Paul. In order to make an improbable run, however, they'll need to overcome a team that thrives where they are weakest.

The rebounding maestros from Colorado.

The Buffaloes are led by Andre Roberson, who is averaging 11.3 rebounds and 3.1 offensive boards per game. His ability to work the glass will limit Illinois' ability to crash the offensive glass.

Roberson will also create second-chance scoring opportunities for freshman sharpshooter Xavier Johnson.

Paul will make any game interesting and D.J. Richardson is the ultimate wild card. As a team that shoots 41.6 percent from the field, however, Illinois is on upset alert.

Don't sleep on the Buffaloes.
