Seems like an overpay. Don’t tilt on one game. Even if Kittle ends up being THE GUY, Burton should be more than fine (and you can always stream TEs in a 10 teamer). And Freeman is way more valuable than Mack.
I’d say no. You’re selling both Burton and Freeman low and buying Kittle high based on week 1 performances. By the end of this weekend Burton could be worth more than Kittle again, like he was a week ago.
