back to the main topic, there's another possibility....to make a player more realistic, with his pros and cons, we can impose something like a "color limit". not even king roger is full of red numbers...he's got 1 red, 1 orange and 4 yellows. rafa is 1-3-2, a-rod 2-0-2, potbelly 1-2-3...
being the average of a created player 70, i won't find it so bad to impose a 1-2-3 color rule, so a player will have no more than 1 red, 2 oranges and 3 yellows. this implies evaluating possibilities to allow 1-1-4 or 1-0-5 setups, in case a player wanted to do some all-around guys, or 2-0-2 (an ulterior red will "cost" an orange and a yellow)
the red one will surely be power...and i guess that restricting it, too, won't be that bad (like 92-93 max).
this way, every player will be at least have some pretty good weaknesses

and hopefully, we'll se more entertaining matches.
edit1: this can obviously come together with some regulations on minimum amount for each skill we're already discussing (maybe 40 instead of 50)...that will be a further step, for now i'd just like to tell that thing.
to give an example, with my rule and the "min 50 for each skill" rule a good baseliner will be:
f: 80
b: 74
ser: 75
ret: 80
pow: 91
volley: 50
speed: 60
stamina: 50
good, but not exactly unbeatable: slow, crappy serve, crappy backhand

i couldn't even use all the 3 yellows i had, that's why maybe a 40-45 minimum limit for each skill won't be bad. anyway, hope u like this!
edit 2: yeah, effectively with 50 minimum for each skills the allowed patterns should be 1-2-2, 2-0-1, 1-1-3 and 1-0-4, things like 1-2-3 requires too many points, and since this rules implies that you are FORCED to have the right colours (to avoid cheesy 89s and 79s) things have gotta be thought out well. again, this is after all a mere embrional idea)
