There are a lot of names to throw out there, but some names I like as lower line options:
Reid Valade is a kid I love for later in the draft. He never stops hustling or moving his feet, and he's a damn good skater too so that makes him very projectible as a bottom six energy guy. I think he could fill a role very much in the vein of Hagelin or Fast if he keeps developing. Probably a candidate when you start getting into the fourth round and beyond.
Evan Vierling is an excellent skater, really good understanding of where to be on the ice, very good shot and ability to get the puck to the right person. Probably not the most creative guy in the world, but he's so smart I wouldn't rule out his ability to over-achieve in that area of the game. I project him as more of a Dominic Moore type. Might be more of a second or third round option though.
Daniel Ljungman has a great shot, very good hands. Average skater, but powerful and balanced. Has shown flashes of having higher-end talent, but it's never materialized consistently. He's a guy who hasn't really carved out a full identity yet, but he's a candidate for a bottom six role. Could anywhere from the second to the fourth round.
Parker Ford is another kid who could go later in the draft who projects as more of a bottom six forward who hustles and attacks for everything he gets. I could see him as a guy who plays a role on the PK, helps the team sustain pressure (even if it doesn't always result in points) and provides a spark. Like Valade, he's someone who might be more of a true late round pick.
