vrana is just as good, if not better than mantha. stylistically a bit different, but vrana+1st+2nd you take that for mantha. also seems like the org was never sold on Mantha early on in his career. i think lot of that got fixed over the years, btu still always had a bit of a negative bias towards him.
for svech, he's going to be a bottom-6 player likely wherever he goes. so losing him it's not a big deal. those guys are typically dime-a-dozen. now if he explodes and becomes a quality top-6er it obviously becomes a bigger loss. he's played well for us, but it is pre-season & against some rosters that are probably on their B or C teams lol.
do think he'll be an nhl player for us, but i think bottom-6er , 20-25 pts will be his reg-season output (82 games). perhaps him and PLD have some chemistry? not sure, but i doubt Maurice gives him a top-6 look unless injuries.
