First of all... some great questions to consider.
Totally agree, I'm cheering for these guys as well and I'd love nothing more than the both of them to jump up the lineup and improve their production. But at this point (as you pointed out) they dont have particularly impressive stat lines.
I think Goldy may have a higher chance of cracking the top 6 just due to the type of player he is with some good skill and skating ability, but both of these need to shine before he can make a good shot at a solid top 6 role.
Jake to me is a very capable 3rd liner and on a good team he could put up some nice point totals, but his playing style currently shows me that he can work hard and make good hits but he isn't a consistently capable scorer. Until JV improves that quality, theres no room for him in our top 6. We really need good scoring forwards in those roles and frankly, Jake could make a great grinding top 6 guy that makes big hits and forces turnovers while being able to score goals and keep up with some of the faster guys, but he just hasnt proved that ability to be a more dynamic player yet.
