Former Miami Dolphins coach Dennis Green has cited his doubts over the side progressing this season.
Green, who is now an NFL Network analyst, told 'Inside Training Camp Live' that there were too many flaws within the squad for them to achieve great things.
In the most unsubtle of approaches, the former head coach voiced his concerns over second-year quarter-back Ryan Tannehill in particular.
"I don't think Ryan's (Tannehill) a great quarterback. So, the key is going to be, how can they overcome losing two great players," Green said.
"If you wanted your quarterback to be a good player and have a great year, then you should have signed the best players on your offence.
"And when you don't do that, you're going to have problems."
After losing running back Reggie Bush and left tackle Jake Long to the Detroit Lions and St. Louis Rams respectively, the Dolphins have been robbed of two of their strongest talents.
And, despite many believing that the side are going to surprise people this year, Green is of the opinion that the failure to replace Bush and Long is yet another serious problem.
"I like Mike Wallace if he's here to play, but Mike Wallace is no Reggie Bush.
"Mike Wallace is a great guy with great speed. He's made a lot of plays down the field, but Reggie Bush has scored a lot of touchdowns.
"And Mike Wallace is no Jake Long, either," Green added, talking about the replacements bought in to fill the void of the departing players.
