I don't recall him ever really trying to run down field. The guy was always looking for an open receiver no matter what.
No with Taysom back there, I seriously hope he doesn't do all that. That would be a waste of talent and opportunity. Taysom should go through reads 2,3 and maybe 4, then take off down field.
If we want Taysom to be a pocket passer 100% of the time, we might as well put Tanner in instead.
