The Duke Blue Devils are currently in Indianapolis preparing for Saturday’s Final Four matchup against Tom Izzo’s Michigan State Spartans. While going through the final stages of preparation, Mike Krzyzewski’s squad is making sure they are mentally prepared for victory.

Everything matters when you are going in to a do-or-die game, including the “Do Not Disturb” signs at the team hotel.

If the Duke players want to avoid any distractions, they have an incredible, custom design to hang on their door that will keep the haters away.

For the sake of Duke basketball and its fans, let’s hope these signs are more accurate than some of the fan tattoos we have seen in recent memory.

Duke and Michigan State will tip-off at 5:09 p.m. ET at Lucas Oil Stadium on Saturday.
