Whie the Bills did not actually practice on Christmas day, Johnson was still listed as out following the death of his mother. Considering her funeral is on Saturday, he may not be available to play week 17 in Foxborough.
First and foremost, our condolences to Stevie Johnson and his family.
Johnson has had a down year following three 1000 yard seasons. He battled a groin injury earlier in the season and is currently dealing with the death of his mother; but the biggest obstacle to Johnson's production in 2013 has been the inconsistency in quarterback play. Johnson had a rapport with QB Ryan Fitzpatrick before the QB left for Tennesee. QB E.J. Manuel has struggled his rookie season, and has ceded time to QB's Jeff Tuel and Thad Lewis, due to a knee injury.
Expect Johnson to have a bounce back year in 2014, you will likely be able to draft him at a discount and get a nice return on your investment.
