Is it?
Hamilton's playing time has been sporadic the last few yers, as he has played on 4 different teams since 2018. His last season as a regular, he posted an OPS+ of 69 with an OPS of .626. With Marisnick's OPS+ of 88 in the last two years, it translates to a comparable (as in if they played in the same ballparks, etc.) of about .700. ( I used Tucker Barnhart for a comparison, as he was ..699/88 OPS+ that year.) So it's more like 73 OPS points.
That year, Hamilton slugged .327 with 165 TB. If we add in his 34 steals to those total bases, and he has 199, his "effective SLG" rises to .395, which would give him an effective OPS of .694, or 5 points below Marisnick.
5 OPS points is about as insignificant as it gets.
There is not much difference. Hamilton will hit fewer doubles, but he will get to second base just the same.
And defensively, they rank out similarly in CF. Hamilton's UZR is roughly double Marisnick's, but the same goes for his innings in the position.
