Clement has a lot of value in a 20 team league, and with Soto's breakout someone is likely to overpay.
Joyce really isn't that good of a prospect long term, but the Tigers moved so many prospects in he'll get a lot of playing time. Projects more as a 4th outfielder, plays good defense but has a long swing. Would likely hit .275 20 HR and 80 RBI in his prime if given a starting job, but who knows if that will happen.
Olson is a finess pitcher who projects as a 3/4. But playing for a bad team, in a hitters park in that division doesn't give him great fantasy value long term.
