Kraft is ok. I wouldn't compare him or Musgrave to Kelce, Kelce is kind of a unicorn.
(Side note for the college stat readers: Kelce's 3-year total college career stats were 59 catches 875 yds 10 TDs, consider that if don't like Musgrave or Kraft's stats)

Agree he's kind of a Mayer-lite, and I think in a draft with average TE depth would be a R2 pick. He timed faster than he seems at 4.69, anything around a 4.7 is good enough for a TE. I think he's got some YAC ability and he can block.
he's what most would call a good value pick in R3 and he also fills a need so it's even better.

IMO Jordan Love has shown more propensity to throw to the TE than Rodgers, I think 50-60 catches for 700-800 yards and about 7-8 TDs combined for Musgrave/Kraft wouldn't be surprising.
Deguara could poach some of those catches as an H-back/move guy as well as the rookies learn the ropes.
