Lot of talk about Brian Cashman, among a few others, being on the hot seat, but Preller is the most overhyped of the front office leaders in baseball.

SD just extended A.J. Preller thru '28 after three 90+ win seasons, 4 postseason appearances in 11 tries, & one win beyond the NLDS despite all those trades and all that money spent.

Won 90, 93, 82, 89, & 79 games with a payroll ranked 6, 11, 3, 6, 2 since 2021.

OVERRATED.

Still think the Royals are going to surprise some folks...

Mets are a bit overranked...

Astros' projections are held down by injury, otherwise they are right there with Seattle...

I’ve actually had two contract offers so I’m really excited. One is less than the other but I’m not quite sure what’s best to my needs so I’ll be working that out but that’s an update for everyone.
