None, keep in mind Franzen admitted because of social anxiety he intentionally tried not to score as a younger player.
But unfortunately nobody has the same development curve in general so that is kind of unfair in my opinion.
While I remain a pretty big fan of what Mantha can be and what he brings to the table when he is on, he ultimately is available if the right return is, just like everyone not named Larkin or our 2019 first overall pick for me. Anyway, his talent and skillset does remind me of Franzen though he has never been nearly as good defensively or physically as Franzen who was underrated often around here over the years... While a better fighter (sadly he gets hurt when doing it) it is only on nights like the last game in Vegas where you see his ability to drag people to areas and totally disrupt systems. Franzen did this often actually, complete coaching chalk talk player. But I get people that bring that, to me he reminds me of when Rick Nash wouldn't drive the net, to date he did it more frequently but when Nash would get stuck in perimeter mode it looked an awful lot like Mantha.
Currently both Mantha and AA are chalk talk players in terms of teams are aware of what they can do. While AA has been more consistent of the two for sure this year, ideally both guys dial that level of excellence more often to where Larkin had been for almost the entire balance of the season. That is important for our current look at the rebuild. If those two cannot develop it, well we are still three years away from the big trend upward in my opinion. We need both those guys, not one or the other and not debating which one might help and which one to move. Both might not pan out, but unfortunately if this turns into Nyquist and Tatar, well tack more time onto that rebuild in my opinion. Both guys have the talent, but it is time, they need to take that next step or the hard choice to move on from both, not at cut rates but what we can get next season needs to happen in my opinion.
