i will toss out the idea of hall signing with boston. there has been some connections linking the two in the past.
boston currently is counting on krecji/debrusk to power a second line. these guys are going to cost more than 10 mill and i think its rather shakey to call them an above average second line.
i argue both krecji and debrusk would be tradable in the current market place and trading them would bring back some assets.
i believe hall by himself... is a safer bet to count on as a second line then the duo of krecji/debrusk would be.
i can forsee bergeron/marchand slowing down in the next couple years... and see them fall into a second line status with the team... i see hall's playmaking ability pairing well with pastrnak and see the 2 of them inherit the top line spot. coyle/ritchie bring some size for a third line. perhaps studnicka develops well enough to be factored into this core equation.
its all about cap management/maintaining depth... having 3 lines that work and are also affordable
sadly i dont see krug staying in boston... with or without hall... i see boston planning to carry forward with mcavoy/carlo eating up the mins and earning the top dollars. then a couple affordable 3/4 guys. and probably a couple kids rounding out the top 6
again it comes down to cap management. if mcavoy wasnt the heir apparant to the pp qb spot perhaps bruins would be forced to pay for a pp qb. mcavoy does need to do that job though to fulfill his potential.
and then grzelyck is an effective enough puck mover to serve as a second guy and his cap hit makes more sense.
bruins might try to find a very cheap guy to round out the team... last year shattenkirk was available for less than 2 mill... someone like him as a 6/7 dman... it just makes way more sense than locking krug up on a 4 year deal at 6 mill
