Pragmatism is one thing but at some point it you do'nt build a winning culture and give everyone something to eat and be exciting about, you build a losing culture that might be hard to change. It affects the internal and external perception of your franchise and their players. No matter what, that's a loser move, you're giving up (like Dallas did). Most players are compe ors and that's their career, and I'm not sure some spurs players who already had to accept everyone wanted them to lose to this year will accept to fold again and miss a chance at playing at the highest level of their sport in the PO, or at least try, just so their team get another pick and push further away an hypothetical time of revelancy that they might not even see because they'll be traded with said pick...
Can't remember what spur twitted at the start of the season that they would surprise some people this year (after all the Wemby buzz and fans wanting the tank) but that's where these guys are... You can't use them and ask to "waste" 3 or 4 years of their career so a franchise they might not belonf to anymore start to contend. that's why unless you really hit the jackpot several times in the draft, building a contender that way is really hard, specially in SA (where it's hard to get and/or keep) stars.
