Imagine if Hoyer and Ricketts had Banks, Santo, Williams, and Jenkins now, they'd be allowing them to walk as FA after 5-7 years through ARB or trading them away over paying them and giving them a longterm extension.
Since 2010, the Cubs longest tenure players are 7 ( Hendricks, Rizzo, Bryant, Contreras, Baez, Hoerner, Happ) guys that came up from minors and just played out contract with 3 ( Hendricks, Hoerner, Happ) getting a little extension.
All good players but no stars
