I don't think Rattler sucks....he hasn't had a fair shot with the starters yet, cause everyone was hurt.
We need to see him with starters and then see what we have.
I'm not big on Derek Carr either but he definitely doesn't suck. We just won't win shirt with him.
However, if we can keep them both at 20 passes a game with the 3 headed monster we have Kamara, Jeanty*, Miller, Edward-Helaire....we should be safe with both QBs.
