Dallas tends to suck in each decade except 20s.
The 80s doesn't go so well. Mark Aguirre and Blackman give you high scoring but nothing else. Tarpley's stats 11/10/1/1/1. I have been going with Sam Perkins but he is only a 14/8/2/1/1. Perk can play SF, PF or C so you can move him to fit in other high value players.
The 90s is rough. I go with J-Kidd. Otherwise you have Mashburn or JJ who are similar to Aguirre and Blackman with scoring but little else. Or Sam Perkins again who had 1 last year there.
The 00s gives you Dirk who is solid - 22/9/3/1/1 - but unexceptional. There are no other alternatives. Nash is 15/7 with no steals or blocks. Finley an adequate wing, nothing more.
The 10s gives you an ageing Dirk with worse numbers or a rookie Luka. I take rookie Luka.
The only high value players are 20s Luka or AD.
