Not sure Conforto can 'really' be counted on to play any CF, but he'd be a great LH bat to add. There are plenty of at bats available for him as an OFer/DH - and he provided good depth in the event of injury or someone sucking (Gurriel). He'd be a huge upgrade over Grichuk and we're getting comp picks back for Ray and Semien, so we can afford to lose one.
It will really depend on the cost. If he wants 4 years/$80M then no, but if he's like 3 years/$40M - I'd be pushing my chips all in.
