MOBILE -- The Dolphins’ hopes at quarterback this offseason are far loftier than landing anyone available at this week’s Senior Bowl.

There’s a decent chance Miami can secure one of its top three options: first choice Peyton Manning, impending free agent Matt Flynn (perhaps the most realistic), or what would be a costly draft trade-up for Robert Griffin III.

But what if the Dolphins cannot? Then they might end up drafting one of the quarterbacks in Mobile this week, or perhaps Texas A&M’s Ryan Tannehill or Arizona State’s Brock Osweiler.

ESPN’s Mel Kiper Jr. said only Andrew Luck and Griffin have first-round grades among quarterbacks, though some consider Tannehill a late first-rounder.

All of the others in the draft have blemishes, including the six in Mobile: Arizona’s Nick Foles, Oklahoma State’s Brandon Weeden, Boise State’s Kellen Moore, San Diego State’s Ryan Lindley, Michigan State’s Kirk Cousins and Wisconsin’s Russell Wilson.

The concern is height for Moore (5-11) and Wilson (5-10). For Lindley, it’s his 53 percent completion rate last season. For Foles, it’s a tendency to force throws at times. For Cousins, it’s inconsistency and decision-making. And for Weeden, it’s primarily age; he turns 29 in October.

Kiper projects three quarterbacks to go in the second round: Osweiler, Tannehill and Foles. Tannehill is not in Mobile because he’s recovering from a foot injury.

The 6-8 Osweiler, who left school after his junior year, has a strong arm and doesn’t need as long to release the ball as some other especially tall quarterbacks.

The issue, Kiper said, is decision-making. Osweiler (26 touchdowns, 13 interceptions, 63.2 completion percentage) “has a tendency to force throws and made a lot of bad decisions. There were multiple games where he threw multiple picks.”

Tannehill, who should be healthy enough to throw for scouts by March, is a former receiver “who has come a long way in a short time,” Kiper said. “Really intelligent player with a strong arm. He’s not a player an NFL team wants starting games in 2012, but he has some skills to indicate he could be an effective starting quarterback.”

The concern, Kiper said, is his play in the Texas game: “That was a red flag … which looked worse when Griffin lit up the Longhorns soon after. He didn’t look like the quarterback he did against lesser defenses.”

As for Foles (28 touchdowns, 14 interceptions), he “has solid mechanics and throws on the move effectively,” Kiper said. “You can’t argue with the arm strength and size. But he’s not as accurate as you’d like.”

The 6-5 Foles is considered by many to be the best prospect among the six quarterbacks in Mobile, but one NFC scout said Weeden was the most impressive through two days here.

Weeden “has a big-time arm, plays with poise and can beat you over the top,” Kiper said. The problem is he’s entering the NFL much later than most because he played minor-league baseball for five years.

“If you think this is a guy you want to draft and develop for a year, he might not make his first NFL start until he’s 30,” Kiper said. “That’s a number nobody will overlook.”

Weeden (37 TDs, 13 picks) said he’s telling teams that his age “is way more a positive than any negative. My body is extremely fresh. I’ve already played professional sports and had to deal with failure.”

But there’s another concern, Kiper said: “He had three interceptions against Louisiana-Lafayette, a couple picks against Tulsa, three against Iowa State. You look at the age factor and the games he was making some bad decisions, that’s the reason he’s probably a third- or fourth-round pick.”

The 6-3 Cousins could go in the third or fourth round; he’s being tutored by former FSU Heisman Trophy winner Chris Weinke. A second NFC scout said Wilson is helped by his arm strength and pointed to Moore’s 50-3 record at Boise State. But because of their height, both are projected to go in the mid-to-late rounds. Though Drew Brees (6-0) has excelled, Cleveland’s Seneca Wallace (5-11) was the only quarterback on an NFL roster this season who was listed shorter than 6 feet.

“I’ve been this height since ninth grade, so I’ve adjusted to it,” said Moore, who threw 43 touchdown passes, nine picks and completed 74.3 percent of his passes this past season.

Wilson was exceptional in his one season at Wisconsin (33 TDs, four picks) but is even shorter than Moore.

“I play tall, I play fast, I have a quick release,” said Wilson, who transferred from North Carolina State.
