Yes, there are some questions surrounding Culpepper, like his knee and his bad 2005 season, but here's the bottom line: He's the best quarterback this team has had since the start of the new millennium. And he's the biggest reason some observers think the Dolphins have a shot to dethrone New England atop the AFC East.
The best fact involving Culpepper -- we've said it before and we'll say it again -- is that his 2005 passer rating, bad season and all, still was better than that of former Dolphins starter Gus Frerotte.
Beasley is a former Pro Bowl selection with the 49ers, and he'll bring the best combination of blocking and catching the Dolphins have had at the position in a long time.
Shelton, meanwhile, will be under the spotlight as he handles the job of protecting Culpepper's blind side. This would be a good time for Shelton to start living up to his billing as a former first-round pick.
On defense, the most significant additions were made in the secondary, where Will Allen, Renaldo Hill, Andre Goodman and Deke Cooper were just some of the guys brought in to improve an area that really struggled last season.
Will Allen comes to Miami with the reputation as a solid cover corner who just doesn't make many big plays, while Hill rejoins Nick Saban after having played for him in college at Michigan State.
The Dolphins also have new faces at linebacker in unrestricted free agents Sedrick Hodge and Keith Newman, who will challenge Donnie Spragan for the starting outside linebacker job vacated by the offseason release of Junior Seau.
Also, don't discount the addition of former head coaches Dom Capers and Mike Mularkey to the coaching staff. Both were highly regarded as coordinators before getting jobs as head coaches, so they should be able to make valuable contributions to the Dolphins.
