Seriously though, I don't have a handle on this situation. I thought Baker was starting to put together a career year, and I was impressed with some of his skills. Without a doubt, he is the starter, and the most well-rounded TE of the bunch.
Only thing is that when he re-signed, Mangini was all about how he is a good blocker, and nothing about his receiving ability. Baker also considered signing in other places, but people only wanted him as a #2-type blocker.
As for Jolley, I think he has receiving skills, but he can't block, and TEs who can't block don't get much PT. Dreesen is a project who will see some time at TE2, but won't be a factor this year. I wouldn't be shocked if the Jets drafted a TE and let Jolley go. He remains a shining symbol of the mistakes of the last administration.
