Sometimes, a change of scenery is all you need.
John Calipari is one of the best coaches of this generation, but constant shortcomings at Kentucky had put doubt into whether he still had any juice left in the tank. So he left and went to Arkansas, trying to revive his prowess in success.
Now look who has his swagger back. The 10th-seed Razorbacks are back in the Sweet 16 after a second-round upset of No. 2 St. John's, continuing Calipari's remarkable first season as the head coach of the Hogs.
To be fair, this was the expectation the moment Calipari arrived in Fayetteville.
