You can easily do both so i disagree with this line of thinking.
Not really. There are is a limited number of scholarships, so coaches have to assess whether a spot is better filled by someone from high school or someone from the transfer portal. Generally speaking, someone from high school is going to have more eligibility than someone from the portal, so I would suspect that most coaches would prefer (all else being equal) to fill spots with kids from high school. If Mario thinks we have a good shot of doing that, then he's not going to prematurely fill those spots with kids from the portal.
