There's never a wrong time to work on improving.
Not in the offseason, not in the middle of the season, not while you enjoy a double cheeseburger at McDonald's and not even right after a win in the Round of 32.
So, while several teams are currently celebrating their secured spots in the Sweet 16, they must realize their performances were far from perfect, and things will only get more difficult as the tournament rolls on.
Fortunately, with just less than a week to prepare, there is plenty of time to work on those imperfections.
Let's take a look at what some notable winners from Sunday need to concentrate on in practice this week.

Ohio State (Beat Iowa State, 78-75): Defending the 3-Point Line
Not many teams can shoot the three ball as well as Iowa State, so the Buckeyes don't exactly have to worry about teams lighting them up to the tune of 12-of-25 again.
But Arizona isn't inept from beyond the arc. The Wildcats are 45th in America in three-point shooting percentage and have five guys capable of getting hot from deep.
Thad Matta is finally getting some consistent offensive production from his players not named Deshaun Thomas. It's now time to combine that with the hard-nosed, sticky perimeter defense that is supposed to be this team's calling card.
Indiana (Beat Temple, 58-52): Offensive Execution
Indiana is the most efficient offensive team in America, averaging 1.161 points per possession. Temple is 171st in defensive efficiency, allowing 0.992 points per possession.
This was supposed to be a display of offensive excellence, but the Hoosiers had heaps of trouble with the Owls' physical play and scored an anemic 0.93 points per possession, marking just the second time all season they've won while scoring less than 1.00 PPP.
Tom Crean's squad can't let that happen again. Its opponent wont always have three starters (Jake O'Brien, Scottie Randall, Will Cummings) combine to shoot 0-of-21 from the field. The Hoosiers must live up to their greatest strength going forward.
Kansas (Beat North Carolina, 70-58): Ball Security
Kansas trailed North Carolina by nine points after playing its third awful half of basketball in a row, but the Jayhawks finally figured things after the break, pouring in 49 points and completely dominating the Tar Heels.
But the offensive woes aren't completely fixed.
Elijah Johnson, Ben McLemore and Travis Releford each turned the ball over twice. Naadir Tharpe coughed it up three times. Jeff Withey and Kevin Young combined for an ugly 11 turnovers. Overall, the Jayhawks had 22 giveaways—twice as many as North Carolina's 11.
Against Michigan, a team that is absolutely deadly in transition with Trey Burke, a slew of shooters, and rim attackers like Glenn Robinson III and Mitch McGary, the Jayhawks can't afford to do that again.
Florida (Beat Minnesota, 78-64): Second-Half Urgency
I'll admit it, I had to stretch a little bit here.
The Gators shot 56.8 percent from the field, hit 10 three-pointers, got to the line 36 times, rebounded the ball and played their normally tough, aggressive defense. They didn't do much wrong against the Golden Gophers.
Which of these Sweet 16 teams has the most to worry about?
However, Billy Donovan's squad, which has lost every single-digit game it has played this year, is notorious for being "unclutch." While that's more of a narrative than anything else, the Gators must play with more urgency when they have a big lead.
They were up 21 at halftime against Minnesota, but came out in a daydream and were outscored 19-5 to start the second half.
The Gators have as much balance and talent as anyone in the country. When they are on top of their game, they can beat anyone. But they need to play a full 40 minutes.
