Well I would Still pick Moore over Severson on the PP. Severson has 12 points on the PP and they are all assist. You would think that yes, he is a good PP. My argument is that 8 out of those 12 assist are secondary assist. So, hes not the direct reason for most of the points. Yes, that can be argued. But even 5 on 5, 15 of 27 assist are all secondary. He has played 78 games, TOI 1,309 and only has 89 shots on the year. To top in off he is a .82 point per game player.
Let's look at Moore now. He has 10 assist on the year and 7 of them are primary assist. 5 of them come from 5 on 5 play. He has only played in 60 games, the majority of his goals come from 5 on 5. His TOI for the year is only 890 and has 71 shots on the year and is a .94 point per game player.
Severson just simply plays more, and that is the reason for getting more points. As a D Moore is a better player this year, on one of the worst defensive core in the league. He is managing a -5 while Severson is managing a -29. Yes, Severson could turn it around because he does have age on his side. But, for me there hasn't been any reason to be hopeful for him.
Right now, if I am Shero I am keeping Moore over Lovejoy for the expansion draft and I'd be looking to make Severson a bottom pairing guy. It is clear that we need help on the back end bad. We need some serious Dmen. You can afford to have a dmen like Severson if your D is somewhat good.
