Sorry adam i dropped the ball on actually answering the question you asked, I see what you're saying, how do the settings of this roster affect the dynamics of the players in the first year draft?
That's a great question that I've been looking into for a while tonight, I ran through 5 simulations of the first player draft and followed up to see what those players current attributes/overalls/potentials immediately upon joining the system.
There were a few players who were casualties of the system and didn't fit with my dream draft, but I imagine you aren't going to have a flawless feeling first year entry draft in ANY franchise regardless of what set/settings/team/players you choose. For pure integration purposes though, franchise does a good job of generating players that fit into to this template. I certainly wouldn't put anyone down though if they wanted to tweak the ratings of the first year draft players at their own discretion. I like developing players and all that stuff too but I really don't want to see all the cool players from real life being put in their place by a bunch of Ramone Russell and game developer models haha.
Long story short, draft works good, I would probably look into tweaking a few things any time I went thru a franchise draft, but you by no means need to, just a matter of personal preference. There were a lot of guys in my draft that were 18-19 with hi potentials that were 40s overall so that was really positive. Also the players that were closer to MLB ready (60 overallish) were either older and further along in their career arch, or they simply maxed out in potential a few points higher than their current overall, so like your classic AAA-AAAA players. A couple occurances of players with overalls and then potentials at a lower number, so that's the only thing that I thought I might consider editing if i were doing a franchise, other than that everything checked out from my end!
I was real glad to see the top 5 guy I picked was an 87 potential and had a ways to work toward it at 57 overall. Too high for a draft pick still imo but it's very reasonable.
Other guys like DOMOROMO (smh) join your club as a 60 and that's their ceiling right there.
Also there is good variety among the talent that teams found. The Angels didn't find a B overall in their haul
Yankees struck a winner with one of their picks and went to the toilet for the rest of them
The A's truly loaded up and didn't falter with the 4th overall pick in Gene Beyer
