This REALLY depends on what you think long term of MAT. You're saying they're the same player, despite them being the same age and Yelich having 16.5 career WAR to MAT's 3.7. In the second half MAT's OPS is .623, so I pretty much flat reject you extrapolating his hot first half to all his missed games. I'm not at all sold on him being a long-term OF solution, whereas Yelich has had 3 excellent years in 4 in his career.
