I still think Jones is the starter when healthy. He will have a shorter leash now. And if he cannot come back in the next few games, Zappe could make enough of a statement to take the job away. One great game isn't enough in my eyes.
I stated this in another thread. When the Pats played the Texans last year, many people were killing Belichick for drafting Jones and not drafting Mills in a later round because they were convinced Mills was going to be a star after he completed 21 of 29 passes for 312 yards, 3 TDs, and 0 INTs. Now Mills is in his last year as a starter and will likely be relegated to back up duty and replaced by a first round drafted QB next year.
