^I see maybe half of those as true losses where there isn't someone to step in and contribute. Reiter hurts on the line but we have some talented tackles and guards here that are young(including 1 who is transferring from Stanford and is eligible next year)..
Cliet and Chandler hurt but there is talent behind them(whether that talent is going to amount to as much as then I don't know)
Davis has had a great career at USF but checks out mentally a lot. Like someone else posted as far as in the locker room goes it could be addition by subtraction for all we know.
As for our #1 CB? Given its his first year at the position it's not as big of a loss as you are making it out to be, I'll miss him more at return man to be honest.
I count 4 that we will miss.. Davis(production), Reiter, Cliet and Chandler. The rest are replaceable.
