Start your career in the CHL and set your periods to 8 mins, you will play roughly three shifts per period (estimated 9-11total per game) and do your best to rack up anywhere from 1-5 points per game and maintain the goals set out for you by the coach. By meeting the required grades in offense, defense, and team play the coach and management will be happy and move you up the lines, which will slightly increase shifts per game. Also, try and not make any infractions, lose fights and honestly do anything negative because it can have detrimental effects. Yet, the goals they outline are easy enough.
Anyway, it will take roughly 10mins to play each game in full guaranteeing that you get the most XP possible. If you play every game in the CHL, league playoffs, and memorial cup you will not only ensure a good draft position, but by following the simple steps above, your player should be hovering around 80+ overall by the time they are drafted.
Now I haven't achieved developer yet, but I can say that following my method and after playing 10 games in the NHL my player is an 86 overall and I estimate in 15-20 games I will be at 90. Also, if you can maintain at least a goal to 3 per game you can net the achievement for first goal, but more importantly you can knock out 50 goals as a rookie.
Its still a small grind but much, much, MUCH faster than last year. As an avid RPG player I just imagine my player as though I was leveling up any RPG character, and the speed at which it can be done, is not nearly as tumultuous and nauseating as years passed. (Or like the length of this solution)
Anyway, remember, always keep your stick on the ice. And if they don't find you handsome make sure they find you handy.
