I would say that Finley is a nice target from the camp, but as he is already seen by some as the #1 dynasty TE, this is not exactly a surprise.
The hype on Eric Decker has been rising lately, and he may be a nice investment, although as he is a rookie, I expect to see more of an impact next year at soonest.
Bowe, while it is nice he is there, has had negative news regarding his conditioning levels at the camp.
Jennings also attended last season, so I am not sure what extra benefit he will receive from another year there, although it definitely speaks well of his dedication to maintaining his performance.
