re: Georgia is losing 5 seniors out of 44 4/5 star players

Just the sheer talent and size difference of the Richt era:

2016 OL group
Isaiah Wynn
6-2 280
Lamont Gaillard
6-2 300
Tyler Catalina
6-6 315
Brandon Kublanow
6-2 290

vs.

2017 incoming freshmen and RS freshmen
Ben Cleveland
6-6 340
Solomon Kindley
6-4 335
D'Marcus Hayes
6-6 320
Isaiah Wilson
6-7 350
Andrew Thomas
6-5 330
Netori Johnson
6-3 345
Justin Shaffer
6-5 355

Maybe they put it together faster in 2017 or by 2019. All I know is you are not going through that wall easily like they did in 2016.

2018 should be a great year for OL and DL but you lose many seniors and potential juniors:

Seniors
Dominick Sanders
Nick Chubb
Sony Michel
Lo Carter
Malkom Parish
Davim Bellamy
Aaron Davis
Reggie Carter
Dyshon Sims
Isaiah Wynn
John Atkins

Juniors
Roquan Smith
Trent Thompson
Natrez Patrick
