Fair comparison but Bradshaw was better. He threw a ton of interceptions as well but saved his best passing performances for big games.
I wouldn't call either a brilliant passer, honestly. Both were big strong armed dudes who could take punishment while someone got open. Terry stayed healthy and went to a great D team, Morton didn't. And when Morton did get on a D team, super bowl.
Don't get me wrong, Bradshaw was better, but the margin isn't all that great.
Morton was good, not great. He's in the convo of Dallas QB's after the obvious top 3, Staubach/Aikman/Meredith. I'd prolly put him in a 5th place tie w/ Romo and Dak w/ White in 4th.
Can't compare comp % between eras, completely different league back then. Over 50% used to be considered good, now it's a benching number.
As you said previously, w/o the injures Morton could've been far better.
