I must remind you fans that Olinemen generally take awhile to become starters. It was a mistake to tout Guyton as an immediate starter. He was no high first round pick like Tyron Smith, Zach Martin or Tyler booker. T FRED was a fluke. These four are all exceptions to the rule that OLmen need time to develop, especially tackles.
You all remember Doug Free? He started for the Cowboys for many years as a solid, good tackle, first at LT, then switched to RT for the remainder his career.
Doug Free did not start and produce until his 4th year in the NFL!!
Tyron Smith was slowly introduced to RT as a rookie, with Free at LT, then they switched positions That T Smith was the best tackle coming out of college and the Boys passed over the ability to draft JJ Watt, whom they also knew would be a superstar, but OL tackle was their most pressing need.
I give Guyton the chance that in his 3rd year, he has gotten stronger, improved his techniques and will disprove all his doubters.
