SR has one thing , one thing over JH, arm strength, not arm talent just strength. My guess the reason why we're starting SR is he's used to running for his life, more so than JH
Haener is not an overly accurate QB for someone whose arm strength isn’t great. If you’re going to be undersized at that position (Haener is barely 200 pounds), you better have some incredible gift that overcomes it. Rattler has that kind of arm talent. Haener does not.
Rattler has also shown a better ability to navigate a pocket when he’s under pressure, and get out and make big plays on the move.
