The Dolphins are auditioning several quarterbacks on Monday and former Florida Gators quarterback Rex Grossman will be one of those, agent Drew Rosenhaus said on WSVN-7 in South Florida Sunday evening.

The idea that the Dolphins need quarterback help goes beyond the fact the team released Brock Jensen, the fifth quarterback on the roster, on Sunday.

It goes to the idea that behind Ryan Tannehill everyone else is either nursing some physical ailment or dealing with a significant lack of ability.

Matt Moore has missed much of practice for most of the past five days -- including Friday's preseason game at Atlanta -- because he's had a sore throwing shoulder. Moore did throw more in practice on Sunday but is still not 100 percent.

Third-stringer Pat Devlin hasn't competed since the team scrimmage Aug. 2. He has a hamstring injury. And there is this:

Although Devlin is a favorite of coach Joe Philbin, the shine on him is starting to fade because, frankly, he shows no signs of challenging Moore for backup status entering his fourth season, and the idea of keeping only two quarterbacks on the roster has to be considered because the Dolphins have more talent at other positions that might be worthy of a roster spot ahead of Devlin.

Seth Lobato? He got three quarters of work against Atlanta in the preseason game and although he wasn't terrible, the fumbled shotgun snap in the Atlanta red zone late in the game was disappointing to coaches. The Dolphins also did not score a TD while Lobato was in the game.

His days on the roster seem numbered.

So the Dolphins are looking to add a live arm in camp that perhaps might increase the competition in the quarterback room. Grossman, who turns 34 later this month, might be that player.

He has played nine years and thrown 63 TDs and 60 interceptions in 54 games (with 47 starts). He was the starting quarterback when the Chicago Bears went to the Super Bowl in 2006.

By the way, am I advocating signing Grossman?

No. I'm advocating looking around for possible answers. Turn over rocks. Look for possibilities.

And here it is: I wish the Dolphins would work out Tim Tebow. He's been working out and working with a quarterback coach. He does have NFL experience. He did help take the Denver Broncos to the playoffs in 2011 and was 7-4 as a starter and even won a playoff game against Pittsburgh.

Is Tebow a great prospect?

No, but he's more accomplished than either Pat Devlin or Seth Lobato.

So why not?
