Saad checks every box but the physical one. He's a big ES producer, a good two-way player, a great net front presence so he could play on the first PP if they wanted to use him there. He can skate and plays a strong two-way game... He just doesn't hit. He does steal a lot of pucks, and that has a lot of value, but this team doesn't need steals as much as it needs a physical presence in the top6.
Long story short, I think he checks enough boxes to be a really good fit. I think we have to accept that they may not get everything they're looking for at the deadline. They didn't last year (no RW for 46), and there seems to be only one winger who is expected to be available, scores enough to play in the top6 and actively plays the body, and that guy is Kreider, but he's not without risk either, he could walk as a UFA or you could sign him to a risky extension.
