Burke would be perfectly fine as their backup PG. They also have Mack. With Teague already their starting PG I doubt they would want to pay Schroeder $$$ in 2 years' time. Getting back x2 valuable first round picks will come in handy. Schroeder's value is unlikely to get much higher playing behind Teague.
I think they would think hard... it seems to me like a fair deal for both parties.
Burke is not perfect for anyone. Who wants a 36% PG who doesn't pass? The only reason he, possibly, doesn't have negative value is his low salary. Nobody is giving up a promising young talent on dirt cheap contract for 2 late first round picks. Get real.
