After a rough down year for the San Francisco 49ers last season, Kyle Shanahan's bunch is (understandably) looking for a major rebound to contention this fall. Such a rebound will likely require everyone in the 49ers' core to be on the same page and working as one.

The Athletic's Dianna Russini reported that, according to sources, tight end George Kittle's absence from the start of the San Francisco 49ers' offseason program is contract-related.

Kittle is entering the final year of his contract, which holds a $22 million salary cap number for the Niners. Per OverTheCap, his contract's $15 million average annual value places him fourth at the tight end position, with Arizona Cardinals star Trey McBride leading the pack with his market-setting four-year, $76 million deal ($19 million AAV).
