Bob, I'm with you.
We could cut the rosters down to 13 players and then create an additional 2 teams (6 teams minus 2 players = an additional 12 guys. If we're creating an additional 2 teams, then we only need 14 new guys).
As for catchers, off the top of my head, we have these catchers: 1 - Boruszok, 2 - Richie, 3 - JR, 5 - Jeff S, 6 - St. John, 7 - Dean, 8 - Bucky, 9 - Reap, 10 - Chin Straps, 11 - Asem, 12 - James W, 13 - Roter (if he comes back)...my apologies to anyone else I left off the list, I just did this off the top of my head really quick.
As for pitchers, sure, you probably won't have a team with three studs, but you could still draft a team with 1 stud (e.g - 1 - Lipson, 2 - Waylen, 3 - Levy, 4 - Vent, 5 - Godard, 6 - Sourlis, 7 - Rocco, 8 - Booth...by the way, these aren't in order, they are RANDOMN)...again, I apologize if I left anyone off this, but I did this too off the top of my head. 1 really good pitcher and then some decent pitchers/inning eaters.
As of right now, you can't tell me each team doesn't have 4 guys who can pitch.
I just think 8 teams makes the league more competitive and balanced. Just my opinion, I'd love to hear what everyone else thinks.
