There are two things I'll be interested to see if Porter goes to the Nets this offseason:
1. I'm always uneasy about giving a big contract to a guy who is coming off of a career season. Is he a young player who is improving and is on an upward trend? Or is this a guy who went all out during a contract year and will revert back to his prior performance? Option 3 is always somewhere in the middle of those two extremes.
2. Even if this is the "real" Otto Porter, he is benefitting greatly from being on the court with Wall and Beal. He is at best the 3rd option for that team, and depending upon matchups, sometimes he is their 4th option at the offensive end behind Morris. If he goes to the Nets he will be the first or second option, working with Lopez. More importantly, he will be the #1 perimeter option.
Right now he draws the opponents' worst perimeter defender. In Brooklyn he will draw the opponents' top perimeter defender. That is a world of difference. And if he isn't actually good enough to draw the top perimeter defender away from Jeremy Lin, then he isn't good enough to make a measurable difference in the Nets results.
I'm of the opinion that this team is going to be bottom 5 again next year, regardless of any changes they make. That roster is so terrible that the players who may be willing to go there aren't going to be good enough to lead them into the playoffs.
