As a Longhorns fan, it almost pains me to say it, but Guyton looked really good against the Rams. He has all the physical tools in the world with his freakish size, extremely long arms, big hands, and athleticism. That was never a question. It was really whether or not he could clean up his technique, leverage, and use of his hands to not let defenders engage him at his body. Granted it was a smaller sample size, but you can already tell he's improved considerably since the Combine 3 months ago. He's likely going to get better with time/reps as well.
Absolutely hated this dude in college, mostly cause he was a huge trash-talker at OU and always gave Texas problems lol, but he's clearly a very good/talented football player and I have a feeling he's going to be our future LT for a long time tbh.
