I don't think anything the Spurs had could beat Isaiah-Crowder-Brooklyn_pick.
But they might be able to get in on Kemba.
If it takes the 18 and 20 picks with declining lotto protections on 20 it's a must make move.
Don't think it takes both; Murray essentially qualifies as a pick as is.
Hurting the value they're likely to receive, is their insistence that someone take a bloated contract and PG being the most saturated position in the league.
Think Nuggets, Pistons, Pacers and Jazz are the compe ion here.
It wasn't about lack of assets to consummate a proposed deal, it's about the lack of attempts. Spurs had a star player that publicly stated that he wanted to play for them and they never even made a formal offer. Oh, there were rumors they made a trade one but unlike every other team's trade proposal which was visible and accounted for, the Spurs offer was never revealed. And even if the Spurs don't publicly announce their trade proposals, you can rest assured it would been leaked someway, somhow through social media via a third party. For all we know, Danny Green was a deal breaker.
If the Spurs didn't have assets to trade for Kyrie, I'm not sure what makes you think they have assets to trade for Walker. Guys like Forbes, Bertans, Laughverne, long term Paddy doesn't exactly make trading with the Spurs more desirable. Even if Jordan was bent on trading him at the deadline, a slew of teams could offer up a better package than the Spurs.
On the Leonard front, the best thing for him is to be shutdown for the season rather than risk any further injury for a team that isn't championship contending with or without him.
No less a source than Wojnarowski himself said, to paraphrase, they tried really, really hard. A formal offer isn't necessary when you can't make a compe ive one.
Walker isn't as good as Irving and there's an even bigger gap in their cache. I don't know that Spurs can trade for him, but I think it's plausible they could. Other than Irving, no recent star trade has been for (perceived) equal value.
