I for one think the ML has at least one more great year left, maybe two. he has 2100 carriers for 9,000 yds, ML normally carries the ball 300 times a year (280-315), he only carried it 111 times in 2015. His running style and his ability I would not hesitate to take him up until 2500 carriers (another year and half or two). He has been incredibly durable over his career with the only surgeries being this year. keep him under the same contract and lets go through him this year and the only difference should be to keep him at 230 carriers to get him a 1,000 yd season and do it again in 2017.
