All the Qb's have been practicing with the #1 offense at times this offseason (but has mainly been Beck and McCown).
I think it is Becks starting job right now. They look pretty impressed with him as he is usually the QB working out with the #1 offense. Henne hasnt looked the greatest at time and at other times he looks okay (not great). I really dont see Parcells and company starting a Rookie QB that isnt doing GREAT in practices. From what i read McCown has done alright but not as good as Beck has. I think the regime is starting to like Beck even more every practice (which i predicted would happen). I have read places where Parcells, Sparono, and even OC Henning has talked great things about Beck, like this;
offensive coordinator Dan Henning said, "Nobody in the NFL has worked harder than John Beck this offseason." He also mentioned that he's thrown between 6 to 7 thousand balls since David Lee was announced as the team's quarterback's coach.
I look to see Beck starting Day ONE against the NY Jets. and coincidentally it will be overshadowed by the Jake Long and Vernon Gholston "Reunion" (even though Gholston will probably play the opposite side than Long.
