Well, only time will tell but I must disagree.I think the only way Bob will be remembered is as "The Old Guy" who won. As someone else posted, Sugar gave him the win just like Colby gave Tina the win way back in S2, and I think Colby is more memorable than Tina (although Jerri was probably the most memorable from that season)
Most Memorable from each season (100% my opinion, of course)
S1-Rich (also won)
S2-Jerri (Tina won)
S3-Lex (Ethan won)
S4-Kathy (Vecepia won)
S5-hmmm...awful cast....hmmmm....probably Shii Ann (Brian won)
S6-Jenna,(Winner) followed closely by Rob C...excellent cast that season
S7-Rupert (Sandra won)
S8-Rob Mariano (Amber won, but he almost counts as a winner)
S9-Ami (Chris won)
S10-Stephenie (no offense to winner Tom, but I still go with Stephenie)
S11-Stephenie Again (Dani won)
S12-Cirie (Aras won, worst winner of all time, couldn't remember him at all)
S13-Ozzie (Yul won, another dull winner)
S14-Yau Man (Earl, had to look him up too)
S15-James (Todd was a great winner, though. Well cast season)
S16-Parvati (winner of one of the best cast seasons ever!)
So out of 16 seasons, only Rich, Jenna and Parvati were both most memorable and the winner.
Also must say that seasons 12-14 were super boring, and seasons 15-17 have been excellent
