Chris Johnson is on this list?
Johnson may have run for over 2,000 yards a couple seasons back, but this is the NFL. Careers can be over in a flash, especially for a tip-toeing running back with declining skill and speed.
In his defense, Johnson could have a bounce-back season with new guards Andy Levitre and Chance Warmack flanking either Brian Schwenke or Fernando Velasco in the middle.
The already-excellent pairing at tackle will enjoy the help inside, but Johnson will need to eclipse his rushing averages of 4.3, 4.0 and 4.5 yards per carry from the past three seasons.
As it is right now, Johnson's contract has only $6 million worth of guaranteed funds after 2013. If he doesn't show that he's worth his current 2014 cap hit of $10 million, the Titans will cut him, take the $4 million in cap savings and pick up a pair of running backs who could replace him.
