I'm not saying Aguilar is better than Merk. I think Merk will be great.He's thrown for some yards sure but don't act like he's some world beater. He threw 24 picks at appy state and transferred to UCLA. There's a reason the big time schools didn't come calling. He might have more experience than Merk but I highly doubt he has more talent. Merk was rated pretty high and had multiple SEC offers, UGA included.
But If the guy with lots of experience starts over the guy with almost none, that is not evidence that something is wrong.
