I think part of what he's saying is that they tried to just add a piece here and a piece there. What became of the team was a mess of similar talent not blended together correctly. By trying to just make the playoffs by adding pieces, some that worked some that didn't, the team was never great.
IMO he's looking at year 2 or 3 for the team to come together maybe sooner if other teams cooperate. lol
Start with the new core group. Get players that are around the same age to grow together, add some veterans in year two and be competing for a Cup in year three.
