I don't know what kind of question that is. Firstly, Timonen was a 10th round pick who didn't debut until age 24. Usually when people make a projectable comparison it's to a player as they are/were in the NHL, not as they were at 18. Maybe he was that good defensively at a young age and was severely underrated as a player; can't say I watched Finnish junior and pro hockey in the early 90s, but it sure wouldn't be a surprise.
I like him a ton and would call Brännström good right now defensively, and I project him as being good. Not sure what's wrong with that. It's awfully hard to be good on the back end in your own end, let alone at 5'9"-ish. But he does a heck of a job, and at worst it shouldn't be a detriment to his top flight offensive skills, and at best could even be a plus going forward. Considering his immense offensive talent and size, the assessment should be whether he is good enough defensively to be a good well rounded NHL player......I think he certainly has that potential. Build from there. He's got the intellect and the compete, but if the expectation being set is elite type defensive play......well, ****. There's not many prospects I throw that label around with.
I simply said I don't see the Timonen comparison in his play style, even offensively. Don't know what the issue is or what more I can say.
