There was another thread about this.
TJones is a nice 3rd RB to have but there are some problems with relying him as an everyweek starter, mainly that 1. TJones isn't that skilled of an RB, 2. The Jets offense is prone to stalling, hopefully that problem is improved upon and 3. There is no set RB at the goal line. Leon Washington was used on most passing downs and saw a lot of time at the goal line. Also, 4. They picked up some new guy AND added Jesse Chatman to the mix, so they now have four RBs to work with.
As you said TJones can/should be nice value as a back up, I wouldn't want to have to start him every week though.
Thanks to deluxe_247 for sig, he is welcome to sail with the Captain too!
