Mike Thomas acknowledges that he's been held back while trying to learn the Lions offense. "We're not so much experimenting, but finding what's the true position for him," said OC Scott Linehan, "while some other guys probably have a little head start on him as far as knowing the offense." Thomas has been a major disappointment, failing to catch a pass in Weeks 14-15 while being lapped by fringe roster types Kris Durham and Brian Robiskie.
