It hasn’t been a great offseason for the Miami Dolphins.

They traded away one of the best wide receivers in the NFL in Brandon Marshall for a couple of draft picks, they can’t seem to lure future Hall of Fame quarterback Peyton Manning to the team and then they fail to land Matt Flynn.

What could make this offseason any worse?

Signing quarterback Alex Smith. 

The Dolphins are interested in his services, according to Omar Kelly and Izzy Gould of the Sun Sentinel. 

Smith has had one good year in six NFL seasons. It just so happened that last season was his best year with 17 touchdowns and five interceptions.

Miami shouldn’t base its future on one season from Smith. They need to look at his entire body of work and then pass judgement. 

Smith has only recorded two 60 percent completion ratings in his six years. He has never passed for more than 3,200 yards in his career and he’s only played all 16 games twice. 

That doesn’t sound like a franchise quarterback.

Franchise quarterbacks win Super Bowls. Look at Eli Manning, Peyton Manning, Tom Brady, Aaron Rodgers, Ben Roethlisberger and Drew Brees—these guys have won every Super Bowl since 2004. 

Not often do teams win Super Bowls with average quarterbacks. It takes a special team with an outstanding defense to put it all together for one run. Smith even had that No. 1 style defense last year, but allowed the eventual Super Bowl champion New York Giants to beat them on the 49ers' home field.

Alex Smith is an average quarterback in the NFL. He’s not even close to being Super Bowl caliber. 

Miami, who lost out on Manning and Flynn, would continue the downhill snowball effect of a horrible offseason if they signed Smith to a multi-year deal. 

They already traded away their best wide receiver in Marshall, which didn’t make Dolphins fans too happy because their offense is completely depleted. 

Signing Smith wouldn’t be as bad, but it would be close.
