Need help with who to buy for my CUT team

What do I need to add to my team if I have 275,000 coins and my biggest upgrade needs are Wide receiver, left guard, Runningback, and Cornerback. My current wide receivers are 98 Tyler Boyd, 95 Jaden Greathouse, and Jaylen Waddle 95. My left guard is 94 Ben Powers. My running backs are Fluff Bothwell 96, and Quinshon Judkins 95. corners are 96 Jaylen Mbakwe, 95 Marshon Lattimore, and 95 Patrick Peterson.

If it were me, I would focus on CB and maybe WR (if you pass a lot). 

For CB, Mbakwe is fine. I'd pick between Lattimore and Pat Pete as to which other one to keep as a primary (I like Pat Pete a lot in the slot personally) and I would grab Legend Tariq Woolen. 6'4" gold ballhawk. He's amazing and is only going for 120k right now. 

That would leave you approx 150k. I would grab maybe a WR. If you value gold Takeoff, you could try to get legend Cory Coleman, but you already have Boyd, so I'd look for more of a possession WR. Possibly grab Stars of the Season McMillan. That card is a menace and plays well above his stats. Would probably swap out him with Waddle. But that's only if you feel like you need a big body WR as a safety blanket.

Awesome thank you

Zack Martin's cards are fast and good at guard. I like Henry Lutovsky there too. Hell even Steve Hutchinson still gets it done.

Go try out Isaac Brown with the plat 360. If you want a more physical HB try Kaleb Johnson. If you're willing to go all out on HB I'd say Bijan and CMC are good all around backs

Options at WR are Nick Marsh and Chad Johnson. I think Marsh especially is a budget beast. Maybe Denzel Boston too but he has pretty low route running stats for this current age of CUT
