The thing is the are only 2 possibilities:

1) is the answer at QB and is just rusty, unpolished, needs time, better O-line, more training, experience a hug or whatever. In this case you have to start him to give him playing time

2) Rg3 will never be a good NFL pocket passer. In this case you still start him every game this year because you still aren't sure about #1, because it does not matter this year is shot anyway, draft position, and finally Colt is probably not the answer.
