I'd swap Tierney and Logan Brown.

Tierney is actually an absolute trainwreck offensively and defensively this season, we just haven't been talking about it. He passes the eye test at least, but the advanced metrics are abysmal. Hockeyviz has his isolated impact as -0.19 xGF/60 and +0.08 xGA/60, but our offense (xGF/60) at 5v5 is +18% compared to league average without and -23% with while our defense (xGA/60) at 5v5 is +4% without and +25% with. He's one of the worst players on our team according to the advanced metrics and would be better suited being as far away from Stützle and Batherson as possible. Stepan is significantly better based on his isolated impacts, somehow.

Conversely, Logan Brown has always had very strong numbers that rival Norris' through their NHL time despite having less favourable linemates and opportunity, plus he has chemistry with Batherson. If DJ Smith wasn't biased towards grinders (or players that can play that game) and gave Brown a leash as long as Norris, he'd likely have had just as much success. Since the start of 2019-2020, both have played 23 games; Brown has had 5 EV P and 3 PPP playing 11:45 ATOI whereas Norris has 6 EV P and 5 PPP playing 15:49 ATOI. Putting Brown between Stützle and Batherson finally gives him the chance he's always deserved and has rightfully earned, just never been given.

Besides, Tierney is better suited to play with Dzingel on the 4th who he's friends with and has played with in the past.
