I feel like when talking about Taliaferro it's one of those things where you just get painted on one of the extremes and all rational conversation goes out the window. You can't say you like him as a back without people treating you like you think he's the next great thing, you can't think he has no future with the team without thinking he's the worst RB ever - it's just one of those annoying things that happens with some players. I think it's clear that LT has shown enough in his limited time to safely say he's a pretty good runner with potential to be much better, "is there room for him?" is the question
I can definitely see a future here for Taliaferro. If Dixon comes in next week or in 2 weeks and proves to be as good of a receiving back as we think he can be plus his clear skill as a pure rusher then I think Buck has a bigger chance of being cut than LT, Buck is just a clear cut receiving back that doesn't offer anything but average at best running - and I'd argue below average honestly. LT has the size of a power back, if he could just learn to get low and drive he'd be a great short yardage back, his big problem in those situations has been him running into the pile standing straight up - and saying he isn't as good in short yardage situations as a player like Forsett is just ridiculous, even without getting any bend he is better than Forsett in those situations, Forsett is a terrible short yardage back.
I think the FO still clearly likes LT, otherwise there's no reason why he's still with the team on PUP. We could have easily just cut him going into the season and the FO chose not to. If nothing else that's a clear sign that they want to give him another shot at some point, maybe that'll be this season, maybe it won't be until next year, who knows.
