While I understand what you are saying. Who are those teams 3rd Catchers? The Brewers had a catching duo that was well thought of and now the short side platoon of that duo will miss the first half of the year. Out of the free agents, internal options, and trade possibilities who do you want that is considerably better?
Imo considering Omar will start nearly every game against righties, for us it is imperative to find a guy who can start vs lefties. Nottingham has an OPS of 1.039 vs lefties in his career and we know he can handle the pitching staff. He seems like a perfect fit for what we need
