one name comes to mind when i pose the question in the topic: plaxico "plexiglass" burress.
he started off terribly, i swear he had like 60 yards and 0 TDs after the first 3 or maybe even 4 weeks, then when big ben got in and got comfortable, plexiglass turned it on, which is great timing for him seeing as its a contract year.
right now plaxico is sitting at 419 yards and 4 TDs. and the best part is, when he was cut by people, he didnt have any of these #s, so whoever was slick enough to pick him up got those 4 TDs and probably about 250-325 yards.
personally, i had him from the draft in one league and got him as a FA in two others. in the league i drafted him in, my WRs were a big joke, i had no 2nd RB to priest, and yet, i lead the league in points with a 6-2 record after 8 weeks (and had i started stokley one week, and i forget which player or two for the other, i'd be 8-0)
the other player i got in one league was tiki barber. someone cut him after week 1, i nabbed him, and urprise surprise he's been a top 5 (maybe even top 3) RB since then, with something like 6 TDs and a good helping of both rushing and receiving yards.
other honorable mentions:
- byron leftwich (he had that streak where he had 300+ yard games, i know for one of 'em he was a sub for a bye weeked mcnabb and he put up 26 for me)
well i cant think of anymore. who do y'all have?
