I'm not sure what you're asking but I would consider Taylor to have value and would look for him as a mid-round pick. I think if he's there around the 6th-7th round and I'm looking for a 3rd RB, I'd be really excited to get him there. 4th to the 5th round, I'd think that I'm reaching a bit.
Basically, he has little upside. Best case scenario he does about the same as last year. Worst case, he gets supplanted as the starter or turnes into more of an RBBC.
Unless he pulls a Curtis Martin from 2004, his days of being an RB1 or RB2 are likely over. As an RB3 for bye-weeks he is probably right about there.
I could see if I went WR and QB heavy in the first couple of rounds, I'd be looking at him around the same time I'm looking at Curtis Martin to stabalize a RB light team a bit. Usually there are one or two squads in a draft who find themselves light at RB around the 5th round, and that's probably where and to whom Taylor will go.
