Did you err ?
I agree that having a multi tool QB is very helpful. Especially if it doesn't come at the expense of his ability to get the ball down the filed with his armYes, so for me Shannahan's offense will be good most of the time, if JG can run it well, so can Fields, Jones, or Lance. JG got enough big plays in 2019, so its not about 50 yard TD's every series.
You make this kind of mega trade up to get the extra plays from the QB and IMO, the extra plays are from those that break down. It happens, your linemen misses a block, miscommunicaton between C and OG, a RB misses the blitz, an all out blitz by the D, or just a great rush by the Edge or Aaron Donald. These are the times you need the QB to make a difference and having the ability to scramble or run, helps a ton. Your offense stays of the field, scores, and helps the D.
