"Being here in Arizona and the hospitality that they've showed me and just the insaneness of it," Bradley said. "When you picture the big leagues and Major League Baseball, this is everything and more."
On Saturday, Bradley and his parents were at Chase Field being chauffeured around what could be Bradley's future place of employment.
"I'd like to get started as quickly as possible," the 18-year-old said. "But I understand it's a process and I have a big decision to make."
Bradley's decision is whether to sign with the D-backs or head to the University of Oklahoma and play quarterback in the fall.
"Being here helps quite a bit to put up against going to the Oklahoma," Bradley said. "Seeing what this town, this city, and after seeing that Spring Training complex, it kind of blows your mind a bit."
Bradley is a hard-throwing right-hander from Broken Arrow who led his team to the Oklahoma 6A state championship in the spring.
His stats looked like this: 12-1 record, 0.29 ERA, 137 strikeouts and 11 walks in 72 innings. The 6-foot-4, 215-pound Bradley was named to the AFLAC All-America roster after his junior season.
He was most impressed with the D-backs' Salt River Spring Training complex and Randy Johnson's National League Cy Young Award trophy.
"It's absolutely amazing," Bradley said.
He said the decision is more fun than agonizing, and that money does play a part in deciding between football and baseball.
"It's not everything, but it's a big factor," Bradley said.
"What it ultimately comes down to is what I want to do with my future."
