Both are great QBs. It's hard for me to predict that RGIII will have more quantitative success (division, league championships) than Luck, but RG will be the one with the explosive plays. I see Luck going more down a path of Brady/Manning where RGIII is going to be great like Vick.
Obviously I say that solely based on their respective races.
I kid, I kid.
Besides, I'm definitely hoping RGIII will be better than Luck so the Titans can control the AFC South for many years to come
Luck has been asked to make and has made longer throws and is more spot on than Wilson or RGIII and Luck has some wheels too.
This is what people generally missed last year. While RG3 and Wilson were running college offenses and throwing every pass within 5 yards of the line of scrimmage, Luck was asked to carry his team and throw downfield. The others are just now learning to do the same thing, and they're going through growing pains while Luck is shining.
