Tanner was running for his life last year and he's a better thrower on the move. Tanner is pretty good at using his feet to create more time to throw.
IMO it is a completely different mentality....when Tanner scrambles it is to throw, when Taysom scrambles it is to run (most of the time) Taysom has had some very good runs this way but I do think he would give our passing game a shot in the arm.
