Three simple answers to the three questions about the in inadequacies of the Jets
The Jets did not upgrade the WR position! They are setting the offense up to fail!
The Jets have done the whole "pick up a troubled WR" twice and they felt it did not solve their issues. They chose a different path, one that promotes continuity of receivers and choosing to develop through the draft.
The Jets did not upgrade the offensive line
Easily the biggest flaw on this team. It deserved attention, but their simply weren't much options. The Jets were high on Decastro in the draft. It was rumored that it was between Coples and Decastro with the 16th pick. Thankfully, they chose Coples. Decastro has looked awful at Steelers camp.
The Jets are hurting Sanchez with the acquisition of Tim Tebow!
At the same time, these critics were screaming "Sanchez needs a fire lit under him!" The jets believe in Mark's ability, but agree that he may have been coddled a little too much. Do we get a QB who can challenge Sanchez forthe starting gig, or can we get an offensive weapon that will pressure Sanchez, but still be a factor. The jets want Sanchez to succeed.
