Johnson LT Williams RT ?

[YorkshireBengal]

Question here for someone who doesn't quite fully understand this. Is a different skillset required to play LT compared to RT? I get that the LT protects the QBs blindside which gives it the edge in terms of importance, but are different skills/attributes required for each position?

Then a follow up question, based on the above questions, do you think Jonah Williams would make a better LT or RT.
