The University of Miami’s two newest quarterbacks arrived in Coral Gables this week with unabashed exuberance and hope for the future of Hurricanes football.

“I’m going to work my butt off and make the most of every single opportunity I get,’’ said Gray Crow, the 6-3, 220-pound Baby Cane from Palm Harbor, just outside of Clearwater, where he graduated from Countryside High School.

“I just love everything about Miami,’’ said Preston Dewey, the 6-3, 205-pound newcomer from Austin, where he played his final two seasons at St. Andrew’s Episcopal School and was coached by former Heisman Trophy winner and NFL quarterback Ty Detmer.

“He’s fired up and ready for this next chapter,’’ Detmer said of Dewey. “He’s a great kid and a football junkie.’’

Both pro-style quarterbacks, interviewed by phone Monday, will begin classes next week and start acclimating to a whole new level of conditioning. Both hope that graduating high school early and arriving in time for spring practice — it begins March 6 — will enable them to get a jump on learning the offense and adjusting to college life.

“There’s nothing bad about it,’’ said Dewey. “It’s all good. I can get my feet under me with the adjustment to college, learn the offense and get stronger and faster.’’

UM will announce the addition of its newest football enrollees next week, with, depending on academic situations, anywhere from five to nine players — perhaps even more — joining the team and counting toward last year’s signing class.

CBSSports recruiting analyst Tom Lemming, who praised both of UM’s newest quarterbacks, on Tuesday released his Top 25 college football recruiting classes for 2012. He has Miami ranked seventh, behind Alabama, Texas, Michigan, Florida, Ohio State and LSU. National Signing Day is Feb. 1.

“Despite what has been going on with the NCAA investigation hanging over their heads, they’re still doing a great job at Miami,’’ Lemming said.

Golden’s impact

“The key is, because of [Coach] Al Golden not having anything to do with the allegations, it hasn’t affected Miami’s recruiting as much as people thought. Miami could get hit [with sanctions], but kids are buying into Golden’s program.’’

Jacory Harris’ departure left junior Stephen Morris and Memphis transfer Ryan Williams — eligible to play after sitting out last season — as UM’s only remaining scholarship quarterbacks. Enter Dewey and Crow, and eventually David Thompson, the Miami Westminster Christian quarterback who would come to UM in the fall if he doesn’t opt to play professional baseball.

Dewey, who will be 19 next month, played five years of high school football because his transfer from a public school (Austin Westlake, where he sat behind current Wake Forest quarterback Tanner Price) to private school enabled him to be reclassified as a junior. He played two years under Detmer, who took over a program that went 0-10 Dewey’s first year and then 3-7 in 2011. But Dewey, ranked the 24th-best pro-style quarterback by Rivals.com, excelled despite the lack of surrounding talent.

He finished his first year as a St. Andrew’s starter with nearly 1,500 passing yards, a 59 percent completion rate and 13 touchdowns to five interceptions. In 2011, after starting 2-2, he broke his non-throwing wrist, underwent surgery and sat out the rest of the season. By then he had passed for nearly 800 yards.

“I’m fine now,’’ he said, though he strained his hip flexor just before last week’s Under Armour All-America game and couldn’t play. “I’ve been resting [the hip] and icing it two or three times a day.’’

Crow, 17, openly effervescent and thrilled to be in Coral Gables, is rated by Rivals as the nation’s 28th-best pro-style quarterback.

Crow led Countryside to back-to-back 10-0 regular seasons. In 2011, he threw for 1,601 yards and 12 touchdowns, with 11 interceptions.

Gifted student

He is very intelligent, coming into UM with a 3.8 unweighted grade-point average and a 1380 SAT score.

“I’m not one of those cocky guys who are all showy,’’ Crow said. “I’m cerebral. I like to read defenses — and pick them apart.’’

Countryside coach Jared Davis described his star player as “very bright and an extremely hard worker. We actually had to tone down his lifting during the season. He’s a big guy, and very technically sound.’’

Now it’s time to start anew for both young quarterbacks.

“I’m pretty sure I’ll be homesick for a while,’’ Dewey said. “But I think this class is special.

“This is where I needed to be.’’
