The lower the pick is nice but it also increases their chances of winning the lottery. There is no guarantee they will be as bad next year, especially if they get 1OA.
I’ll just chalk it up as Hall being damaged goods.
Respectfully, I will say that I do not see your logic. The Arizona pick is looking more and more like a top 12 pick this year. You raised the perfectly legitimate concern of whether Arizona wins the lottery, but I study all 31 NHL organizations and that is not exactly a team on the rise. The 2021 Arizona first-rounder is very likely also a lottery pick.
The Coyotes are essentially capped out, which will severely inhibit their ability to re-sign Taylor Hall. They will be left with a team which can boast a very capable coach in Rick Tocchet, a very good blueline and two solid netminders -- but that's where the good news ends. They are perhaps the thinnest team at center in the NHL; Dvorak and Stepan are good 3Cs and Schmaltz is a borderline 2C. They lack the cap space to make a big acquisition here. At both wings, the Coyotes are very problematic. They have some nice scorers in Kessel, Keller and Garland but all three lack other dimensions to their game. I would go so far to say that Arizona is the softest team at F in the league. On the bottom 6 they have Crouse, Fischer and Richardson, but they are losing Richardson to free agency and I would go so far to say that their top 2 lines are the softest in the league. Their blueline -- though talented -- is not particularly physical either. Quite frankly, they are not a difficult team to play against aside from a frustrating and well-executed defensive system, they lack dimension and they are unable to score much due to not only these factors but a severe lack of offensive capability up the middle and a team-wide inability to win battles in the dirty areas of the ice.
What I'm saying is this: Arizona is a likely lottery team this year and they're a likely lottery team next year. There's some help on the way with talented prospects like Barrett Hayton and Jan Jenik and Viktor Soderstrom -- but they are all two years away from making a significant impact at the NHL level. In my mind, the problem lies with GM John Chayka; until he learns to weigh actual factors which impact hockey games with the same emphasis as analytic data, he's never going to ice a winning team, it's just that simple.
