Not really, his defense was elite his first season, that was probably an outlier, then he had a couple of poor/below-average seasons and has since settled in as an average/above-average fielder since. He's also gotten better as a hitter, consistently. He'll project for like 25-30 WAR in the next three years alone, Mike Trout is so good that unless injuries start to settle in he could easily produce surplus value in this deal, or more likely at least break even. That's worth it for literally one of the best players of all time, good on the Angels, hopefully they don't squander this opportunity like they have thus far in Trout's career.
