This is a keeper league so looking to the future is important. Soto was looking like a stud his rookie season. Sophomore slump or one and done? Suzuki seems to keep getting better and better. For short term, you need Suzuki's consistency. For long term, Santana might be worth a gamble over Soto. But, will he end up being that much better than Soto? You're talking about using #1 WW priority on someone who has not taking one major league at bat. If you are really sold on him being a SUPERSTAR, then I'd make the move. If not, I don't see it being worth it
I think with having Susuki on your team, it really becomes a matter of choice on your part...whom do you believe is the better guy? Also, could you deal Soto over Santana to someone who believe Soto will bounce back. Also, I dont personally see him being a #1 pickup, then again it's your call.
That's a good question. Santana isn't likely to come up until early June because of the MLB salary rules, and in an 8 team keeper league I'm not sure I'd ever want to have two catchers on my roster.
That said, I can see the attraction of Santana over Soto (who's been disappointing since his superb rookie season). I think it comes down to who else you think you might use your #1 waiver on. In a way, this is league dependent. Is yours a league where people put in lots of waiver claims? Or do they hold onto high waiver spots to jump on players as they get called up? There is some freedom in having a low waiver priority - you can put in lots of waiver claims without much cost to you.
Perhaps the biggest factor is Strasburg. If he goes on waivers when he's brought up in June (again, the salary rules) then it's worth hanging onto that #1 spot for him. If he's already on roster somewhere, then go for Santana. I mean, what the hell, why not?
