Well, first, it's highly unlikely we don't get anyone else.
Second, maybe. I couldn't see the C's winning the East with that lineup and winning the title. However, if the brass conceded the East title, kept the starters minutes down, took a mid-seed, then yes, if Doc rode his well-rested starters hard in the playoffs--and they held up--the C's might just pull it off when rotations tighten in the playoffs.
