Quick break down of rostered players:

Josh Oliver:   Unproven but promising.
Looks like a top flight prospect on paper but his rookie year was marred by injury. Only healthy for 4 or 5 games in 2019 - he was unable to create chemistry with Foles or Minshew - both of which were too frequently pressured to rush passes or scramble. 
 
James O'Shaugnessy:  Decent contributor if healthy. 
Has proven to be a worthy target in the passing game and a satisfactory blocker at times. Recovering from knee injury may keep him from contributing early in 2020. Not the worst #2 TE around, but likely won't be 100% in September. 

Charles Jones: Bit of a project with H-Back skills. 
Jones played some H-Back at Tulane and could be used as a lead blocker there instead of a full back if he takes to it in camp.  Gruden has employed the H-Back at times before. Jones has experience receiving from that spot as well as the F and Y positions more common for TE. Not the fastest or most nimble athlete but displayed sure hands in college career.

Free Agency -

Some players who are still out there that might be considered on mid tier or cheap deals:
Charles Clay
Nick Vannett
Delanie Walker
David Morgan
Luke Stocker
Tyler Eifert 

I think Charles Clay could be a good veteran presence that could still contribute a bit on the field at 31 years old.

Draft - 

This year's crop is universally heralded as weak compared to recent years. Top prospects include:
Kmet
Trautman
Hopkins
Bryant
Moss
the other Bryant
Parkinson
Breeland

A number of these guys may me hanging around in the 4th, 5th or 6th round but may not be big contributors year one.
