Pumped but Skeptical about the Tkachuk brothers - it that just me???

So I'm super pumped about us having both of the Tkachuk brothers - we saw their chemistry in both the 4 Nations and the Olympics. However, we also saw they can get in each other's way. No denying Brady is a super talented and brute force player just like his brother. But 1) are they gunna distract each other on and off the ice? and 2) That spark of them playing together may be a result of them playing together for a short period of time for Team USA. Will it translate to an entire 82 game season?
