have no idea about signing a vet TE

I do know that they played Hemingway a ton during preseason, and as an inline blocker, and outside threat
Don't know for a fact that McVay had him dialed in as a primary factor from the TE spot over the course of the 2017 campaign, but from what I saw it made me think he did.

If they don't have Hemingway as a prime participant in 2018, he'd be a pretty easy cut after camp.

Sure looks like they need to deal with their own free agents, and be highly selective about acquiring new faces
On offense, there could be a some significant issues should they lose Watkins, and Sullivan.
At that point, Graham could be a one year deal (probably 2 year based on commitments, and Demoff)

I still have some hope for Hemingway.
But from some of the quips in the news, sure sounded as if Talib would be their "big play."
