I believe a team has to consider worst case scenarios in order to be prepared to win.
Thinking Nichols will remain healthy for the full schedule is hopeful, risky, and great if it happens.
On the other hand what if his achilles lets go in the preseason.
I am not sold on the proclamation of Dom Davis as #2. My concern is a lack of experience at the pro level leading to a tendency to abandon reads and rely on athleticism to escape pressure and make plays. Maybe I am wrong and he will be great.
I could see Cato, Mitchell Gale, or Jonathon Crompton all being as effective as Davis. Not sure about Crompton but the other two are out of work with few options so may come at a reasonable cost as well.
Is Drew Willy going to be available? He was ahead of Davis on the depth chart last time he was here and it may be possible to pick him up for a song and a lap dance. Would need to look at the contract for that to work.
