Cook made his debut in relief of Taylor last week and had little support from a group of receivers that dropped one pass after another.  Cook would finish they day 14 of 30 with no touchdowns and two interceptions, but the seven drops by his pass catchers, including a would-be touchdown to John Metchie, skew the reality of his performance quite a bit.  While Cook did throw a pair of red zone interceptions, it’s going to be interesting to see if he takes as different approach when not handed a huge deficit to come back from.

So now for Cook, rather than entering a game already down 21-0 as he did last week, it’ll be a scoreless start and hopefully a game in which he gets a little bit of support to see what he can do.

An undrafted free agent out of Missouri, Cook managed to stick with the Jets practice squad after a solid pre-season and now finds himself about to line up as a starter.  A mobile quarterback with more than adequate arm strength and off-the-charts leadership in college, the Jets will use this week to begin their evaluation of Cook in determining whether or not he has a future with the club.
