If I was a Morecombe fan I'd be very pleased with this appointment. Adams has the ability to sign good players on a low budget and is very canny and streetwise. His time at Argyle was a success- it was really just the last few months of his tenure when things started going wrong.
Adams made mistakes in the summer of 2018 when he signed some dodgy defenders and paid the price for that. Even then, the team were unlucky to be relegated on goal difference. He probably feels aggrieved at being sacked, because all managers have blips in performance.
I didn't like Adams tendancy to push players too hard to return from injury- it seemed to make them worse. I also didn't like it when he refused to speak to the Herald- not a wise move considering it is one of the main sources of information for the fans. The tactics were ocassionally boring, but Argyle were certainly not a "long ball" team, they played good football when everything was working well.
Overall, Adams was a good manager for Argyle. I don't reckon he had a very large playing budget at his disposal either (I'd speculate less than Ryan Lowe has been given). I think he will learn from his mistakes and get better. I'd say he is one of the better managers Argyle have had in recent seasons and has a bright future in the game.
