Trainers Todd Pletcher and Chad Brown stopped by to wish McGaughey well, while Lukas and Bob Baffert, who didn't have a horse in the race, spoke warmly of him, too.
"It was a wonderful victory for Stuart Janney and Dinny Phipps. There was a lot of karma there that rewards people that have been great to the sport," Lukas said. "I saw Dinny before the race and told him that I thought it was going to be his turn and I was a little worried."
After watching replays of the Derby, McGaughey was more impressed with Orb.
"The maturity he showed yesterday in everything he did, from his Derby day to his experience in the paddock, which was tremendous, going in the post and the way he raced, it was kind of amazing to me," he said.
Orb will see some familiar challengers in the 1 3/16-mile Preakness. Mylute and Oxbow, who finished fifth and sixth in the Derby, along with Will Take Charge (eighth), Itsmyluckyday (15th) and Goldencents (17th) are likely to face off against him again.
"As good as he is, if Goldencents rebounds and gets back to his Santa Anita Derby effort, I think we have a chance to be right there," trainer Doug O'Neill said about his horse.
Among the new horses possibly joining the Preakness field are Illinois Derby winner Departing, Sunland Derby winner Govenor Charlie, Southwest runner-up Fear the Kitten and Bellarmine.
Lukas, a five-time Preakness winner, thinks the next race will be the toughest for Orb.
"If he gets by that, he gets to go back home to Belmont and run right out of his stall," he said.
Golden Soul, who finished second in the Derby as a 34-1 shot, will likely pass on the Preakness and point toward the Belmont Stakes on June 8, trainer Dallas Stewart said.
The final leg of the Triple Crown is where some of Pletcher's Derby quintet could land, too.
Revolutionary, third in the Derby, and Overanalyze (11th) will likely run in the race.
Pletcher wasn't sure about future plans for Palace Malice and Verrazano, whose four-race winning streak ended in the Derby. Charming Kitten will go back to turf races.
