Hill vs Siemian why is there a debate?

Why is no one accounting for the fact that the Saints might not want to play him as the joker the rest of the year because then they'd probably lose Taysom in 22 as he chases his dream? I think they'd lean toward giving Taysom another shot at QB1 to ensure keeping him a Saint.
Hill looking more and more likely a cap casualty. Same with Winston, but I do think we'll probably bring Winston back only because we can afford to bring him back with his market going to be nothing.
