I have been a HUGEEE Biggio fan since he was drafted.. However, he does not contribute to run prevention for us, his D is not Gold Glove, and he was sucking at the plate prior to injuries. As far as Moreno, you can't expect anything from a rookie, who has no AAA time. Especially to the level of replacing Semien.
Even Vlad jr struggled first time up. Adel, Kelenic, Larnach, Duran, on and on didn't move the needle when they were called up at first and certainly did not provide replacement value for someone like Semien, not to mention Gold Glove D= Run prevention.
On the pitching side, the list is long of sophomore slumps and guys like Pearson not making the impact we thought they would when they were in the minors.
Regardless, our offense was great last season and will probably still be sufficient. We need to do better at run prevention. Bullpen, defense and be able to cover the loss of Ray.. I am also worried about Ryu, health and age...
