Drafting poorly? What? I'm pretty confused by what you're saying. Where did I ever imply that? Actually, I'm proposing it be much more difficult to draft well if you read my post in its entirety. Right now, I play with my housemate who writes down all the potentials of players and he never fails to get all A potential players.
What I'm proposing is to hide that potential bar, and make it less meaningful. Look at Jason Pierre-Paul. Potential? Absolutely has the potential and athleticism to be the most dominant pass rusher out of this draft class. Whether or not he FULFILLS that potential sh ould be based on other variables that ultimately are more essential to the development of a player.
For instance, JPP is going into an organization that has consistently developed elite pass rushers, so he can learn from some of these guys and be developed under some of their coaches. Also, how will Perry Fewells new scheme dictate his development? These should take precedent over the potential rating. Does this mean he should be an elite player down the road in Madden? Absolutely not. But all of these things should dictate whether or not his chances are high.
Right now in M10 you draft a player like JPP to a terrible team with terrible coaches and no history of developing pass rushers and his 79 w/A potential will ultimately (and 100% of the time) result in an elite grade. I'm not saying potential shouldn't matter, just that it should be secondary to these other variables.
On the flip side, there is absolutely no reason a player with a 75 ovr and C potential can't one day (and ON RARE OCCASION) develop into an elite player given the right circumstances and opportunity. When Tom Brady was drafted was he considered to have a high ceiling? No. He had arguably the best coaching staff in the world, a system conducive to his style of play, and a savvy veteran to sit behind and learn from. In these rare instances, mediocre players should sometimes rise into good to elite status. If you want to do this by having potential change over time, then do so. I would argue there is no need (but thats not an important argument).
Now where in the world do you figure I'm saying you can draft poorly and be rewarded for doing so? You still want to target players with high OVRs and potential, but what YOU REALLY WANT TO TARGET PLAYERS THAT FIT YOUR SCHEME/COACHING STAFF. If they have high potentials and overalls, all the better.
