Pretty tall order getting Jennings, DeRozan, Nene, Lee and Marvin with $40 mil. DeRozan would want the full max from a team like Brooklyn. That's $25 mil. That leaves $15 mil. That might get you Jennings and Lee or Marvin, but most likely just Jennings and some smaller signings.
You might be right, but I still think they'll go after at least one big signing like that, even though it'll just be a guy who's not really a star, like Derozan.
After that, they'll go after one or two lesser guys (e.g. Jennings, Lee), and then just look at minimum contracts for D-Leaguers / veterans.
They're not completely devoid of guys who can give them minutes already on the roster. Bogdanovic is a decent shooter to have on your bench. I think Thomas Robinson is fine. RHJ and McCullough might give them something.
That's why I said in my first post that they should use this season to conduct D-League tryouts on their roster to find one or two guys who can give them 10-15 minutes a night and provide at least one NBA-level skill. Then buy up some 2nd round picks in the draft and try to find one or two more guys who fit that profile.
If they follow that plan, they'll end up with a team of second and third tier veterans who they will need to lean on very heavily in order to get to 40 wins or so on the season. But it'll be doable.
This is the reason I think this year is so important as far as getting a top pick out of the Nets. Next summer and the summer after, they'll have cap space to acquire rotation pieces that can keep them respectable. I think they'll once again be in the 35-45 win range after this year. Unless Brook suffers more long term foot problems. Then things could get really exciting for the Celts.
