HO you sure do sound like to know a fair bit about the SEABL. Its a shame you are not correct on the financial side, as is alot of basketball fans out there. Yes it does cost all clubs 50k to play in the SEABL , but that cost sends the teams to Brisbane, Canberra, Mt Gambier, and Tasmania. So if you take out the flight costs the SEABL is probably alot cheaper than it is to play in a city based competition like the Central Bank SA State League ABL(hang on what is it called this year, you seem to change it every year). It is entirely up to the clubs themselves as to how much they spend on their teams that play in the SEABL and im not sure where you get the $180K mark, as most of the SEABL teams have two imports and the rest are locally developed juniors that dont get paid.
As for your judgement that the SEABL is over rated, ask the Souther Districts why they moved to the SEABL ?? Southern Districts have been winning the QABL consistenly for the past ten years and needed a BIGGER CHALLENGE, and it seems to me they are getting it, with the womens team currently second bottom on the ladder. The Lady Spartans have won the QABL 10 of the past 11 seasons so it clearly shows the difference between the SEABL and QABL in the women. As for the men, yes the Spartans are the second best team in the SEABL at the moment, but im sure they have enjoyed the challenge of a competitive game each week.
As for the Central teams where have they finished at the ABA Nationals the past five years, i think it may have been seventh or eigthth (out of eight teams) every year.
As for why so many AIS players get a gig in NBL have you ever thought that it could have something to do with the competition that they play in and the fact that they compete against highly talented players each and every week which helps with the development, and so when they make the move to NBL they are not scared and intimadated.
You also say that the Big V and waratah are closing in on the SEABL, and yes you might be correct with that, but i think if the tenth placed team in the SEABL played the tenth placed team in either of those competitions i think it is pretty easy to work out who would win that game. The SEABL depth is by far greater than any other league in the ABA. Each week every SEABL team has to play hard, where as Big V and Waratah and probably Central the top teams are only challenged every second or third week. As for the Big V entrants in the past couple of ABA Finals, Dandenong are a past SEABL team and Hume City are a past SEABL team, so clearly not much depth in the Big V !!
