I strongly disagree. We signed Roberts who will cost us ZERO if he doesn't make he 53. We have committed $500K to LeCosse.
The signing of Roberts means very little. We may add another TE or two before the end of August. We need camp competition, camp bodies, and competition for the Practice Squad.
1) LeCosse will definitely be on the 53 to start 2019. IMO, he is also likely to be on the 53 to start 2020.
2) In addition to LeCosse who is a lock to make the 53 this year, Roberts will compete with Izzo, Anderson and Beck (and perhaps another acquisition) for an additional roster spot or two.
BOTTOM LINE
After 4 weeks, we will have Watson and LeCosse. We ill also have Develin on the 53. We will also have at least one TE on the Practice Squad; Beck seems most likely.
Finally, we may or may not have a 3rd TE on the 53 to start the year, and may or may not have a 3rd TE on the 53 when Watson comes back.
