Have you seen this O-line class? Or are you just looking at a 4th round label? Do you even know anything about our guy? How can you have confidence in a guy you know nothing about? The guy is potentially moving to Center even though he hasn't played it. Gino was a 4th rounder and had a year to study behind Birk. Sorry if I don't just buy into hype that he can handle that.
A drop depends on whether the QB placed the ball in a good position. If the WR has to flip around and do acrobats to even get a hand on the ball, I will be a heck of a lot more forgiving as opposed to a guy just sitting there and having it bounce off his chest.
And dude, the same thing applies to missed tackles. If a defender is getting flushed out of a play because the NT is not doing their job and a guard is getting a free run at the safety and the safety is just able to get out of that block and can't square up on a RB who is already running at top speed, well most times that is going to be a missed tackle. You have to evaluate everything is going on in the game as opposed to zeroing in on someone with the purpose to criticize.
