Agree 100%. With young QB's, especially true dual threat guys, they tend to hold onto the ball too long because...
1.) they aren't used to the speed at this level.
2.) they are used to being able to get out of trouble with their legs.
I was impressed with Martinez in how quickly he made decisions with the ball (granted we only are seeing highlights). I'm guessing Frost drilled it into his head to make a quick read and then tuck it and run if nothing is there. You're better off with a young guy like him tucking and running too early than holding the ball too long. Also, Nebraska's D looked really bad, almost no pressure and guys running pretty wide open, so that makes things easier for him.
If we jam at the line of scrimmage with our big corners against their undersized WRs, I think we could frustrate him and force him into tucking too much or holding the ball too long. Its been said on here a lot, but I feel a LOT better about Taylor and Lewis' speed in containment this year than trying to stop him with last years' defense. Improved D line and Landman's sure tackling up the middle, and I'm feeling really good about slowing him down. Also, I think he might be susceptible to some punishment too, as he runs a little upright and isn't the biggest guy.
