first draft had a 6'4" spd 99 WR (to pair with moss), next draft had a 6'4" spd 99 acc 99 CB... that's some good luck
i'll post a new fantasy draft franchise I just did after i fiddle with some contracts that should set you ahead of the game if you've been having some trouble, and it'll give you guys that are fast and will improve very quickly in OVR ratings.
besides that draft pick exploit, something i really like doing is taking a crap qb and trading him for vick (since its easy to improve THA and AWR which are his only weaknesses he gives you an insane advantage over any other qb you could have or ever draft in madden)... just take someone like joey harrington, kerry collins, or david carr and max him on one of the minicamp drills, then through the first year as he's starting he should get 2AWR and 1 THA every 5 weeks (and every post season game)... once he hits 95-99 OVR, you can trade him straight up or with draft picks for M Vick and avoid his killer 28$mill signing bonus.
Vick goes to 99/99/99 very quickly too and cause of his speed is useable till he's ancient. The main reason to do this is so you can take randy moss in the 1st round (who's impossible to trade for) instead of having to choose. CPU team players dont improve and that's why it works, but there's literally not a single other player worth using this kind of trick for...
