Given Foerster, who is a year younger, is 4th among forwards in TOI, I don't think age is an issue with Torts. He's patient with Foerster's offense, b/c the potential is there, and meanwhile Foerster does all the little things to stay in the lineup. He's 3rd among forwards in xGFrel. Just has to learn to finish and turn that shot into goals.
Brink had a good start then tailed off, not uncommon for a rookie. Torts doesn't sound like he's given up on the kid, just doesn't feel he's NHL ready, especially off the puck.
The Flyers need a LW, this is a chance for Lycksell to grab a steady job in the top 9, though he may be auditioning for a spot after the TDL if a couple forwards are traded. I'd be surprised if Tuomaala comes up for more than a couple games at the end of the season, as good as he's playing at LHV, he's still really raw.
