Great deal for the Padres imo
Absolutely nothing to indicate the numbers are a fluke, elite level prospect translating those numbers at the MLB level at a premium position.
San Diego will come to regret this deal in a short 2-3 years. You dont hand a player that type of deal after 143 games. That is barely one season and we have seen plenty of players burst onto the scene only for the rest of the league to figure him out and he becomes a liability to the team.
Time will tell and I really hope I am wrong. But history has proven that players due tend to level off over the course of their career when teams figure them out. Kris Bryant is a prime example. Alex Rios closer to home is another. Jose Cruz Jr. is another people will remember. All players that burst onto the scene in their first season only to come down to earth later.
Handing him a 14 year commitment is plain stupid. That is my opinion.
Just to counter this
Kris Bryant: if the Cubs signed him to a similar deal after 1st year they would have (per Fangraphs $ value) received $178M of value through the first five years of the deal. I don't think he's magically changed from a ~135 wRC+ player to a below league average hitter due to 147 bad plate appearances last year. There is a very fair argument in there that they got that through the traditional pre-arb/arb system and now don't need to pay him going forward (but that could change if he comes back in 2021).
Alex Rios: Slashed .273/.321/.390 in his first 1000 MLB PA's. Was in a RF platoon with Eric Hinske before the 2006 season started. Not even in the same stratosphere (e: still my boy though, deserved way more than what he got here).
Jose Cruz Jr: Had two seasons above 110 wRC+ in his entire career (Tatis his been at 150/149 his first two years).
Now, the obvious example to me is Brett Lawrie (.293/.373/.580 in 171 PA in 2011, compared to Tatis at .301/.374/.571 in 629 career PA), but Tatis was a far higher ceiling prospect and we're still talking almost four times the PA here.
Anyways, the real loser is Acuna, since that already garbage contract looks legitimately WOAT-worthy now.
