That might sound appealing to Dolfans, who crave a more dynamic offense than the deficient version they watched last year.
But Sims-Walker is not the way to do it. He certainly would upgrade most rosters, but not enough in Miami to warrant whatever he'll cost.
NFL buddies like to conjure scenarios during the offseason. The emergence of Twitter takes daydreaming public.
Sims-Walker tweeted in response to Marshall: "I'm trying to pull a lebron *hint*"
Marshall came back with: "I'm D-Wade and @MikeSimsWalker is Lebron."
Sims-Walker retweeted with the hash tag #makeithappen.
The problem for Sims-Walker is the Dolphins already have a player like him, only better.
His name is Brandon Marshall.
"Mike Sims-Walker is too much like Marshall -- big, physical, possession guy, kinda slow," Scouts Inc. analyst Matt Williamson said.
The Dolphins certainly need to improve their passing game, especially in the red zone. But they seem to have the pieces in place. Whether it was quarterback Chad Henne's inconsistencies, a lack of chemistry or flawed play-calling, the Dolphins struggled despite having adequate receivers already on the roster.
Where the Dolphins are most lacking at receiver is with a reliable speedster who can stretch the field. Hartline has handled that role, but they can do better.
"If Miami is going to add a wide receiver," Williamson said, "it has to be a pure speed guy, someone to really stretch the defense and open up room for the running game and the underneath stuff to Marshall and Bess.
"Speed is the key. Especially considering all the needs Miami has, if they go wide receiver, they've got to go with a home-run threat. And Henne, despite his faults, can sling the long ball."
Sims-Walker wouldn't help much in that area. He has averaged 13.5 yards per catch for his career. Sims-Walker had 11 plays that went at least 20 yards and none that went at least 40 yards last season for the Jacksonville Jaguars.
Hartline's downfield numbers were better than Sims-Walker's when you consider Hartline played only 12 games and Henne went deep far less frequently than Jaguars quarterback David Garrard. ESPN Stats & Information charted nine completions for Henne on passes that traveled at least 20 yards in the air, compared to 18 for Garrard.
Hartline averaged 16.3 yards per catch as a rookie and 14.3 yards last season. Hartline had 10 plays of 20-plus yards and one play of 40-plus yards last season.
