When Matt Cassel is ready to return to the starting lineup I think there is an excellent chance that Thigpen will be listed as the second QB and Croyle as the Third on gameday.
Brody Croyle played a very solid game in Baltimore and I believe has solidified his position as the backup QB as long as he remains "available". If Matt Cassel is unable to go this weekend Croyle will start, and Thigpen will be the number two QB. If Cassel does play I think Thigpen will be listed as the number two QB and Croyle as the three.
What is my reasoning for this? I believe that the coaches are working on a package that features Thigpen on the field in different situations. I think we ran on series in this formation last week. I know everyone was saying that Croyle was pulled for a series, and I think they choose to run the Thigpen package then to settle Croyle down, but I think we would have seen it at some point anyway. The first play was a running play with Thigpen (there was no chance he had any intention of throwing). This will add a little variety to the offense and if we show this package defenses will have to take time to prepare for it. On gameday Cassel will start, Cryle will be the backup, and Thigpen will be the specialty QB.
Here is the problem. This means we have 3 QB's active on gameday and as a result have 1 less position player or special teams guy on the active 53 man roster. Here is why Thigpen will be the 2 and Croyle the 3. The third QB can dress and not count against the active roster on gameday, but if he comes into the game he has to play the rest of the game unless he gets hurt. By naming Croyle (the backup) the 3, if Cassel goes down and we think he will not return, Croyle goes in and finishes the game. As Thigpen is the 2 he can enter and leave the game as many times as he wishes. This is how Miami dealt with the issue last week. Pennington was the starter and Pat White was the 2nd even though Chad Henne is the backup.
I thought I would just throw this out there so if Thigpen gets listed as the Number 2 on gameday upon Cassel's return we understand that it is not a demotion for Croyle but a sign that the Chiefs intend to run a special package of plays for Thigpen. I may be totally out to lunch on this one. Let me know what you think.
