Frankly, I always though of Russ as the QB that people wished Vick was. The good mobility, and good arm (yeah Vick had good arm strength, he was just wildly innaccurate), but with good football intelligence and especially the intelligence to use his legs more wisely. That's really my modern era 'comparison,' though it isn't a direct comparison TBS. Vick was always too quick to run and never really learned to become a pass-first QB that the NFL tends to demand. He was, like RGe also rather careless (some say fearless) about getting hit, also unlike Wilson.
For past QBs, he is Tarkenton to me, with better arm strength and better ball security, though Fran was never known as a fumbler IIRC. They played in different eras, though, and the comparison strains a bit. One thing though, is that in Tark's day, virtually nobody was a 'pass first' offense. Minnesota generally had a decent to outstanding running game. Tark just made all of the highlight reels, and in many ways was one of the drivers moving the NFL to the pass happy league it is today.
