If the smurfs each have a 1/1000 chance of being Marty St Louis and all it costs you is Par Lindholm and Mason Marchment to cycle through them, why wouldn't you?
Does anyone understand the concept of expected value? Let's say there's a lottery where a ticket costs $1 and the jackpot is $1,000,000. Basically, the number of tickets sold determines how much each ticket is worth. Each ticket has an equal chance of winning, so if a million tickets are sold, each ticket is worth a dollar of expected value. If you could buy every single ticket, you'd expect to break even. Now EV gets interesting if you start messing with the number of tickets, the price, or the winnings. If only 500,000 tickets are sold in the $1 lottery for the $1m prize, that means that each $1 ticket is worth $2 in EV. You'd be a fool not to buy as many tickets as you possibly can. Even if you can only get 10 tickets because the rest get bought out, if you can afford the cash outlay it's the smart play.
I bring this up because stockpiling these smurfs could be totally reasonable from an expected value perspective. How much is Marty St Louis worth? Hell, how much is a good 2nd line winger worth? That's your payout. Now consider what the cost of those lottery tickets is. In my eyes Par Lindholm sucked every bit as bad, and Mason Marchment is a complete nothing. So we're paying nickels to cycle through some lottery tickets where the potential payout is pretty darn big. Of course, it's a lottery with those 1/1000 odds, so we'll probably never win and end up losing a couple nickels over it, but imagine that we do win it. Imagine that we do pick a St Louis one of these days and what a huge coup that would be for the franchise.
Trying out a few shitty small tweeners every year costs the organization practically nothing. Considering the potential payout and the cost of getting those tweeners, it could be a positive EV transaction.
