Well the shoulder injury Pennington had usually takes two years to fully recover from.. And he has shown it in jets camp.. In fact, if you read the jets blogs during training camp, they were raving how his arm seems much stronger with his higher velocity throws....
Pennington was quite impressive in Jets camp when you read their training camp blogs...
Moreover, Chad only had 2 int's during camp, while Clemens had 8 int's.. Pennington was clearly their starter this season before Tannenbaum got a hard-on for Favre.. It was much more an "owners decision" to go for Favre than a coaching decision.. It has been shown that Tannenbaum has loved Favre for a long time, and wanted him in a Jets uni.
