In my honest opinion, that is complete ********. You don't desperately need experience. Sometimes being raw and hungry is better than experienced. Or... you can have a perfect combination find good chemistry like Rust and Cullen. If a rookie is making rookie mistakes, then you make the decision to bench him. Don't just expect him to make them.
I think "experience" is one of the dumbest and most overused concepts on NHL teams. You can find examples that work and examples that just completely suck.
Until he proves me wrong, he deserves a shot. Why couldn't we say the same about Murray last night? Murray only had a few games of NHL experience, yet he was our second best player (by a large margin) last night. In your theory, that shouldn't happen and Zatkoff should get the start since Zatkoff has a lot more NHL experience. That's using your reasoning against you.
When people have unironically, in complete seriousness, suggested playing Sidney Crosby between Eric Tangradi and Beau Bennett for half a year "to see if it sticks," maybe, just maybe, it's time to re-evaluate the entire thought process that could lead someone to what was, in retrospect, a preposterous failure of an idea instead of doubling down and potentially making the same exact mistake in assuming some other guy you know absolutely nothing about is a top of the rotation pitcher "until he proves me otherwise." It will blow up in your face 1000 times for every 1 time it works.
You don't assume Simon, who you have little to no knowledge of, can go be Patrice Bergeron (a first line capable player in his draft year) until he "proves otherwise." You ease him in to see what he can handle--and what he can't. If he can handle more, you give him more. If he can handle that, you give him even more. If he can't, you step him back.
That's how Wilson ended up with a trial on line 1. Put him in a limited role. Started scoring. Expanded it a little. Kept scoring. Went scoreless for a little while, got stepped back a bit. Then he got hurt, so the story will continue next year. Simon's not past step 1 yet.
You don't take an intern and make him Executive Vice President because one line of business shrunk 5% last quarter and you overheard him say something clever while you were pouring coffee.
Experience is one variable. Not knowing anything the **** about Dominic Simon, what he can do, how he handles NHL minutes against bigger, better players than he's ever played against and wanting him on the first line, anyway, is another major one. What you're suggesting is the type of thing the Islanders used to do back when they were a laughingstock. "Hey Lachance is supposed to be good, let's make him a 1 D." Ended up as a huge disappointment.
