I know you love having to get the last word in and I kind of respect that, but you're kind of punching above your weight here. Sure, not every qb needs to have a gun in that system, but it most certainly helps Milly. I'm not sure if you know the nuances of a cover 2 defense or not, but it really helps if the QB has an arm that can deliver the ball quickly over the top of the CB who is passing off the WR to his Safety who would but closing that gap relatively quickly - all the while getting the throw over the OLB who is taking the curl throw away. The receiver doesn't literally stop in that zone or the olb is going to take that throw away all day. What you referenced were option routes which I do not deny exist off of a vertical passing game. However, the most effective passes in that play or system are the throws that occur in the space between the lbs and safeties. It's a big time plus if the QB can make those throws into tighter windows. I would liken Zach Allen's skill set to Greg Paulus. Not a great arm by any means, but pretty accurate and mobile enough. If TCU has another QB with a better arm and an equal grasp of the offense, it's no wonder why Zach isn't playing. I'm going to bow out now and I'm sure you can finish.
