I am not convinced Bo is the right fit for these 2 wingers.
Undoubtedly Pearson and Toffoli have chemistry together (does help their being besties too), but look at the origins of that success ......
With the LA farm team, the Manchester Monarchs, they were centered by Linden Vey, a pass-first player.
When called up to the big team, after a few games they were put together on a line with Jeff Carter (another pass-first player) to form the heralded "seventies line"
Bo is not a pass-first player. He is often a bull in a China shop,, taking on the whole opposition to barrel his way thru. If ne weren't so good at faceoffs, he'd make a great power winger.
The best pass-first center we have in the system is Petey, but he sucks at faceoffs. Next best (imo) is Jasek. He was great with Lind and Bailey, but has been moved back to the wing with John Stevens return.
Carter did get a lot of goals by being a net front presence, and Bo does too, so there is that.
I think Pearson with Bo and Toffee with Petey works just fine
