It sounds exciting. It might even be plausible. But by now, the Lions surely have learned a few lessons, haven't they? Reggie Bush apparently will be available when free agency opens March 12. The Dolphins reportedly are ready to let him go — too expensive, too much of a luxury, not an essential piece. Hey, a perfect fit for the Lions! No. Oh, if the price dropped considerably — below $4 million per season — maybe it would work, in theory. In reality, no, it's not wise to invest in a niche running back who's about to turn 28 and has seven seasons of NFL wear. Sorry if that bores you. But this is the time of year when someone (besides me) needs to keep the shiny, enticing objects away from Lions general manager Martin Mayhew. Bush is shiny and enticing. So is Denard Robinson, whom Mayhew called a "Swiss Army knife type of player." Swiss Army knives are cool and Robinson is intriguing, but before collecting more fancy cutlery, the Lions need everyday silverware just to set the table. They have too many holes elsewhere and too many salary cap issues to add another pricey offensive piece, especially one past his checkered prime. Bush has topped 1,000 yards once in his career. Last season, he rushed for 986 yards and caught 35 passes, one shy of a career low. Could he make a short-term impact? Of course he could. Since speedy Jahvid Best was sidelined a year-and-a-half ago with a concussion when the Lions were 5-0, they've gone 9-19. Best's career probably is over, and Mikel Leshoure showed no explosiveness after returning from an Achilles injury. Leshoure and Joique Bell still could be a decent tandem, but outside of Calvin Johnson and Matthew Stafford, the Lions have no big-play ability. That's why Bush is enticing, and several reports link him to the Lions. The Dolphins seem prepared to move on, although that could change. From The Detroit News:
