Yes, like Hutson.. they create their offense in very similar ways and both have question marks about how well they can defend. Lane's is size related, Buium's is not size related but more IQ related. So you're not going to invest a top 5 pick into what you already have in your system with the same strengths and similar weaknesses.
But yes, if you are picking top 5 why would you double down on what you already have with similar question marks? You'd obviously go for the position and things you need on your team. Hitting on Buium means you have to find the right trade for Hutson. Hitting on Iginla or Sennecke impacts us in no way but gives us dimensions we need.
There's question marks at everyone but no you don't trade down now, you trust your scouts and pick the highest rated guy on your list and account for, if everyone has the same amount of uncertainty, who makes us better compared to our in house alternatives if they hit.
