The Tennessee Titans have been pretty bad at selecting quarterbacks over the past decade. Whether you want to talk about Vince Young or Jake Locker, the Tennessee Titans just have not hit the mark.
However, Marcus Mariota is one of the most hyped and well-liked quarterbacks to ever join the franchise. He has the off the field poise and maturity of Jake Locker (possibly better) with all of the athleticism of Vince Young (again maybe more). Now combine that with an accuracy that we have never seen before and you have the current Titans quarterback.
So, that is all good and well, but you play the game on the field not on paper or on websites.
