If the Niners are interested in improving at tight end, they need to look no further than veteran Zach Ertz, who has been training at Stanford with his old quarterback Andrew Luck. Ertz signing makes sense given 49ers' current health and roster makeupAilments are already starting to pile up for the Niners. Last season, Tonges stepped up in a big way and played well for the Kittle-less Niners. If the 49ers wanted to make room for Ertz on the roster, they have the means to do so. Yet, if he wants to play for a good team in a familiar part of the country, then the red and gold is an obvious choice.
