Voted for Mangold- based on where each player is at in his career- Mangold is a perennial Pro Bowler based on name recognition but his play declined last year along with the rest of our O-line. I don't think too many Jets fans are that enamored with Kerley (we like him but don't think of him as our #1 receiver), Howard (unless they're still celebrating that Wayne Hunter is gone), and especially Hill (some of us, myself included have high hopes for him because he's only going into his second year).
The correct answer is Keller, Landry, Harris, Pace, then Moore, and Slausen. On the list I'd have to say Mangold, but only slightly, and Marty should suit him better. That and playing with new guards should re energize him. Moore is on his last legs, and Slausen is an average pass blocker, and a jag run blocker. Thankfully Idzik does not ascribe to homerism. Keller is just a big receiver, who cannot stay on the field, and he's only 6'1". Landry was good compared to what we've been used to, but he is undisciplined, poor in coverage, and unlikely to have another injury free year. Harris will, be gone after next year, and hopefully some youngsters will step up, and make Pace unnecessary, even at his reduced rate.
