The fan-base has been wanting a TE with more "pop" since the early 2010's. Frankly, I don't see the need for it. Schultz played very similar to Witten, and served as a security blanket and go-to-guy on key downs.
Is he a top 3 TE? No, but he can certainly develop into a top 7 sort of guy.
sorry No comparison to young Witten who consistently beat LBs and safeties even the pro bowlers.
Schultz didn't shake and juke coverage guys in one on one near on a level that Witten did.
Plus Witten was a very good in-line blocker
in Prime of his career ; nether Schultz or Jarwin are effective in line blockers.
And you're right, he will suit our offense just fine and adequately.. until Jarwin's healthy return.
Schultz worked well with sensing openings in zones and working underneath in moving the chains, but he doesn't have Jarwiin's quicks and ability to race the deep middle seams.
