but are there any true 5's in the portal?
Short answer...yes, quite a few true 5s in the portal. I had posted some of the guys I found most intriguing a few days back.
2019 Basketball Transfer Portal
Not sure it's EVERY name in the Portal, and I don't know how accurate the eligibility part is...but you can filter by position. Plenty of great size in the PF/C positions in the portal.
From a size/production stand point here's the best bigs in the portal I think
Joey Brunk - 6'11" played in 33 games with 13 starts 18.6 mpg, 7.6 ppg, 3.6 rpg, 1 apg
Barret Benson - 6'10" played in 32 games with 5 starts 9.4 mpg, 2.2 ppg, 3.0 rpg
Miles Brookins - 6'10" played in 28 games with 15 starts 17.3 mpg, 5.0 ppg, 2.6 rpg
Dominik Olejniczak - 7'0" played in 33 games with 22 starts 18.3 mpg, 5.3 ppg, 3.0 rpg, 1 bpg
Javan White - 6'10" played in 33 games with 2 starts 8.4 mpg, 2.0 ppg, 2.0 rpg (his previous year at Oral Roberts though 27.5 mpg, 10.2 ppg, 9.0 rpg, 1.3 apg) didn't seem to get much court time with Clemson
Jordan Brown - 6'11" played in 33 games with 1 start 10.1 mpg, 3.0 ppg, 2.1 rpg (was a 5 star HS prospect would have 3 years eligibility left)
Cameron Lard - 6'9" played in 24 games no starts 12.5 mpg, 5.6 ppg, 2.8 rpg his previous season 26.4 mpg, 12.6 ppg, 8.1 rpg
