Franco did have a very strong 80 game start, but Andujar had his “start” over a full 149 game season. No flash in the pan half season of greatness. Also, Andujar’s WAR is driven down by his freakishly bad defense, not his very strong offensive numbers. The defensive improvements may or may not come, but he has the tools to improve as he’s quick, has good hands and a great arm, just seems to be mechanically unsound.
The big difference between Andujar and Franco comes in the types of contact. Andujar’s 2018 saw him make “soft contact” only 14% of the time as opposed to Franco’s 22% rate in his shortened rookie campaign. Hard contact rates were in Andujar’s favor as well, 36% to 28%. When you’re hitting the ball harder 8% more of the time, you’re going to have a better shot at keeping your offensive game in good position. Franco walks more. Andujar has better power and a far better ability to hit for extra base hits. Andujar also proved to be able to hit for high average in the minors which Franco didn’t. Franco’s final full season in the minors saw him hit .257. Andujar hit .315.
Slapping a label of Franco on him is wishful thinking from a pink hat.
