I feel at this time, Clemens has a better understanding of how to get the job done. Admittedly, he is unorthodox in the HOW,. but he always seems to find a way to make a play.
Davis may indeed develop, and while I agree, may have more "upside", he doesn't look like the same guy who "won" a job last year. IF he would have played the way he has played in camp THIS YEAR, he would never have made it out of training camp LAST YEAR.
Cause for concern for me, has been his lack of accuracy. The indecisiveness is just from inexperience, but when he does make up his mind to throw the ball, he misses on more throws than he connects on.
