If I'm Otto Porter and it is between the Kings and the Nets max offers, I would look at the rosters and pick the Kings, without a doubt!
Agreed, he's a good fit with us and if he looks at our roster he should see a lot of potential. However, we are in the west with a lot of strong teams and star players. There's even other rising young teams to join last year's play off contenders like the Lakers and T-Wolves. It's going to be tough to rise in the west, whereas in the east it's perhaps easier for him to get play off basketball sooner than he will here.
Why? Well, first the Nets do have some talent and at times played a lot of teams close last year. Sure they've lost Lopez but they have got Russell who came into the league highly rated. Hollis-Jefferson is a talented kid. Lots of cap space as well to sign FAs and no reason to be bad because they don't own their draft pick. Maybe they can put something together that can sneak them into the play offs. I guess there's a question over the team's ceiling but if Russell breaks out and reaches that star potential and Porter breaks out and becomes a better scorer in a greater role, with some smart additions they could improve.
With that said, there's more talent here and he's a good fit in our starting line up. So in an either or choice I would take our team over theirs even in a tougher conference, though some might prefer their chances out east at having greater play off chances and success in the play offs.
