Ok, I am a very opinionated person (in case that wasn't already obvious) So I am going to give my initial views on some of these proposed changes:
1) The Combine: I think this undermines the value of a good scouting department on your team. And what, are you going to invite 1500 people to this thing? 50 Rounds * 30 teams. I think if I had a good scouting department, that I worked hard at, I would be pissed at this notion... do your own work figuring out who is worth getting, instead of having it all served to you on a platter. This smacks of, let's be like football. And what type of drills can you do? Hitting in a batting cage is nothing like hitting live pitching. You can show off your throwing ability I guess, but hard to show your range, or defensive prowess in a drill. You can measure speed, but not baserunning acumen. I don't like this one bit! (can you tell?)
2) Moving the draft date back. At first when I read this I thought that ment, earlier... wrong. It means 3-4 weeks later. So you screw draftees out of their first season in professional ball to go to instructional leagues... Hey, I am all for teaching these kids fundamentals and all, but there is NO substitute for playing a game that counts, period! You cannot simulate all the different things that can happen in a game, and the fluke things that can occur. There is alot that can be done in instructional leagues and they do have their value, but basically forcing that on all draftees does not make sense... ALSO if this is the case, the draftees have no insentive to sign quickly. Now, if you don't sign quickly, you miss out on a year of developing and proving yourself to the club. So you will see more people holding on to the last minute to drive up prices. Great for Agents and draftees, bad for clubs.
3) Removal of Arizona League and Gulf Coast League: Not sure I see this as a big deal... teams have "extended spring training" and instructional league things if they need to work with guys, but they do lose playing the game benefit. I guess since the Astros are not involved, I have not seen what advantage this gives a club.
4) Pioneer League becomes 3rd SS division, allowing all 30 clubs to have one. This seems reasonable.
5) Appy going Co-op: What the heck does that mean? If a team wants to spend the extra money to have a second SS team, why should they be prevented from doing so? Seems like MLB is worrying too much about such a minor expense... as was pointed out in a quote in the BA article, it is costing them about the price of a Utility Middle infielder. Can MLB be so cheap as to dump the Appy league over something that is less than $5 Mil? I don't like this move.
6) Short Season begining earlier: WHY? What advantage is there to this, except that it forces new draftees to all go to somewhere else the first year. So now we bring in alot of the reasons I hate the draft being pushed back. I could see this being a good thing only if the draft is held EARLIER in the year... I DO NOT like the idea of slowing down player development/movement in an organization. Not allowing players to play the year they are drafted, IMO does that. If they need 2 seasons of Short Season to develop, you find that out based on how they perform in the first Short Season. Then you have spring training, and half of a season to "instruct" them before they begin a second Short Season. They need to check their reasons for why they are doing this. I figure based on those reasons, I am against this too!
One other comment: By reducing each club to AAA, AA, A(high), A(low) and SS only. You will cause ML clubs to not draft all 50 rounds anymore, or do alot more DFE, which may or may not be good. If your draftees each year go into Low A and SS the next year, it also kills the chance of some guys to develop, if they take time to develop. Look at guys like Backe... He changed from OFer to pitcher... How much harder would that be, if you now eliminate an entire team worth of roster spots for young players? Also for those players who were drafted in the last couple of rounds, how many of them might not have been drafted, because a team looks at their projected rosters, and go, I have no more slots, and then passes in the draft. Most teams don't pass until mid-late 40s in the draft rounds... with 25 less roster spots to fill, how many teams will really keep drafting for all 50 rounds? Piazza may never have been drafted that way.
I think they could do somethings to change the Draft and Minor League baseball, but I don't like many of the current "suggestions". I don't see where this adds value, more than it hurts value.
I guess I don't know as much as I thought I did, if these are "good" ideas in MLB eyes.
