About George Springer (Mets fan)

Hello. I'm a Mets fan and we've all heard the rumors that Springer might sign with the Mets due to the new ownership purchase of the Mets. I've watched some highlights on Youtube and have watched glimpses of him during the postseason. He seems like a really good player, but it looks like he has some flaws in his game. Could you guys speak on how you feel about him. His strengths and weaknesses, his upside and his defense as an outfielder. Thanks.
