No one is giving us that for UPL

Ivan Prosvetov is already better than Luukkonen, why would anyone buy out a better goalie and give up assets for a liability?

Vejmelka trade is quite plausible for draft day and something the Yotes would consider and probably take.

I do see in your comment that you don't know the value of these players and that is OK, considering most AZ fans don't know these players.
Kassian = meat bag to shoot pucks at and serve bench penalties, no value
Keleman = fair bottom 6 guy with some potential, 4th rd pick
Ritchie = 4th line/fringe guy that is good as a net front menace and miserable player to play against, 3rd rd pick
Brown = 3rd pair D, big stay at home defender that rarely gets noticed because he does his job well, 3rd/4th rd pick
Mackey = fringe guy/AHL that has a motor and can be a PITA player, 6th rd pick
Prosvetov = up and coming huge goalie, athletic and smart, working on quickness and positioning, 1B ceiling. Value is difficult to measure during his development.

In the system guys to keep an eye on are:
Kolyachonok, Duda, Fedotov, Lipkin, Lutz

HUGE PASS from Ottawa

I wouldn't trade Brannstrom for Vejmelka straight up (who seems bit overrated on CF)

I'd rather keep JBD too

I'd take my chance on an UFA goalie or explore another trade
