Like Perriman, Robinson was a first-round "bust'' who had his career resurrected in part by Mayfield believing in him. The Browns are now also trying to extend Robinson's contract, and he told cleveland.com he wants to be back.
"I like Greg and I like everything he represents,'' said Dorsey. "With regard to could he be our left tackle, we've had ongoing conversations with his representatives.''
At 26, the former No. 2 overall pick is still in the prime of his career. He'll have a veteran offensive line coach in James Campen, formerly of the Packers, guiding him.
"I totally expected Greg to play well,'' said Dorsey. "He's a very young man who has incredible athletic gifts. Sometimes you have to be a little patient with guys like that. You have to earn their trust. He did everything he was asked and everything we thought he would since we signed him in late June.''
That doesn't mean Dorsey has given up on undrafted rookie left tackle Desmond Harrison.
"He got exposed to a lot early, and it's always good to step back,'' he said. "Getting thrust in that position was hard but I thought he was really good. So now how do we grow? Learn from our mistakes, build from our mistakes and move forward. This offseason, he has a lot to build on because he's a mighty talented individual.''
