Both questionable passers, but like you said, fluidity in running and overall play, such as quicker release, Hurts definitely has the advantage. QBs like Hurts and Dak are not the type of guys you will get consistent franchise play around them.
Hurts was awful last year, especially against us when Quinn was pressing the WRs from the snap and there is nothing impressive about him. There system is maximizing his skill-set, but he will level off quickly IMO and if they give him a huge contract, that will suck for them.
