Ereck Flowers, Offensive Guard
Ereck Flowers is exactly what the Bears brought in with Germain Ifedi, but proven. Flowers made the switch last season from tackle to guard and it paid off greatly for him. After seeming like a bust, he earned a nice payday from the Miami Dolphins to be their guard of the future.
At his size, he was almost impossible to get by as a guard as according to ESPN Stats & Information, he had a career-high 92% pass block win rate. He also was an absolute force as a run-blocker on the inside with his size and strength.
Ifedi is in a similar scenario as the Bears have already said they plan to make the switch to guard for him. Ifedi may turn out like Flowers and breakout as a guard, but why not get the proven asset in Flowers and lock him up for the future?
Obviously, the Bears do not have the cap space to obtain all five of these players. Any of these five players would just be a significant upgrade for more than likely a pricier option (outside of Hooper) over the next few seasons. The Bears did a great job in free agency, but this is how they could have done better.
