Henne and Tannehill are pretty much comparable, Henne isn't better. Henne was a statue with no pocket presence as well. At this point, I am ready to say the Hennehill moniker is apt.
Tannehill will go on to have a solid career as a stopgap/backup QB just like Henne, but its becoming more clear he isn't a true starting QB.
Henne is a below average QB bwt the 20's once he gets in the red zone the space is smaller things happen quicker and he is over matched and either turns the ball over over settles for fg
RT on the other hand is an average QB bwt the 20's and above average in the Red Zone, scores more TD and less FG without turning the ball over... much rather have RT over Henne any day....
