The Patriots have agreed to trade third-year tight end Jacob Hollister to the Seahawks pending a physical, league sources tell Field Yates of ESPN.com (on Twitter). The Patriots will receive a 2020 conditional seventh-round pick in return. 
The Seahawks had four tight ends on their 90-man roster, plus incoming undrafted free agent Justin Johnson. But, with Will Dissly coming off a knee injury, the Seahawks felt the need for some reinforcement.
Enter Hollister, who has just eight catches to his credit across two injury-filled seasons in New England. The Seahawks aren’t necessarily expecting a ton out of Hollister, but could provide valuable depth support if he manages to stay healthy.
Ok, so we don’t have any big name TE, I don’t remember seeing the Pats draft one, so who is going to play the position?
They signed Austin Seferian-Jenkins
Trade for Brate or Rudolph or Ben Watson comes out of retirement and signs.
I thought they resigned martellus now that his brother is there.
Perhaps the Pats just go for a block TE and call it in. The Pats had Gronk do a ton of blocking last year. Hence why his stat lines were low.
Ryan Izzo is the one to watch I think
Looks like they are very high on that LaCosse kid they signed from Denver, but this deal has to be a pre-cursor to a corresponding move at the TE Position. The TE plays a huge role in the Josh McDaniels offensive scheme so something else must be in the works here.
I would have loved to see them sign UDFA Logan Parker (S. Utah) or Dax Raymond (Utah State), but In Bill We Trust!
So that’s why they have Sefarian-Jenkins. Kid tore it up as a receiving tight end at The UW
