Seattle wants a vertical TE as well, and Dissly can be a great compliment to that.
Unfortunately you can only fix so much in one off-season. O-Line and playmakers at WR & TE will come next year.
This year the clear emphasis was getting more physical run blockers, and a better running back.
I get it, and am on board with the plan. 3rd string TE in the 4th rd, with a future of being the backup doesn't scream great value in the 4th rd to me. If you think he can be a starter then you have to do a lot of projecting because he isn't there yet. The definition of a reach.
It's the 4th rd curse, E.J. Wilson, Kris Durham, Chris Harper, Kevin Norwood, Mark Glowinski, Rhees Odihambo (last 3rd didn't have a 4th that year.) Tedric Thompson (still early on him, I don't like him at FS personally. Not enough speed.)
I chalk it up to a quirk on how JS does his draft board. The way he sets it up leads to having reaches in the 4th rd.
He has a horizontal board. He looks at the position of need that has the fewest players remaining in the 4th, and that is who he drafts.
Which leads to these results.
After you get passed the 4th, and have taken your "reach" player the horizontal board opens up, and you can just take who you like, and that is why their 5th rounders almost always end up better than their 4th rounders.
I keep waiting for JS to adjust this... but nope, it continues.
